Caparo was founded by Lord Swraj Paul , in 1968. Sixteen companies within the group were put into administration in October 2015, leaving three to continue trading as normal. One month later, Sanjeev Gupta , head of Liberty House Group , announced that his family had bought
272-412: A BOS process is manufactured in one-twelfth the time. Today, electric arc furnaces (EAF) are a common method of reprocessing scrap metal to create new steel. They can also be used for converting pig iron to steel, but they use a lot of electrical energy (about 440 kWh per metric ton), and are thus generally only economical when there is a plentiful supply of cheap electricity. The steel industry
408-531: A brittle alloy commonly called pig iron . Alloy steel is steel to which other alloying elements have been intentionally added to modify the characteristics of steel. Common alloying elements include: manganese , nickel , chromium , molybdenum , boron , titanium , vanadium , tungsten , cobalt , and niobium . Additional elements, most frequently considered undesirable, are also important in steel: phosphorus , sulphur , silicon , and traces of oxygen , nitrogen , and copper . Plain carbon-iron alloys with

At the community level, much of England is divided into civil parishes with their own councils ; in Greater London only one such parish, Queen's Park , exists as of 2014 after they were abolished in 1965 until legislation allowed their recreation in 2007. From 1994 until
816-444: A change of volume. In this case, expansion occurs. Internal stresses from this expansion generally take the form of compression on the crystals of martensite and tension on the remaining ferrite, with a fair amount of shear on both constituents. If quenching is done improperly, the internal stresses can cause a part to shatter as it cools. At the very least, they cause internal work hardening and other microscopic imperfections. It
952-428: A ferrite BCC crystal form, but at higher carbon content it takes a body-centred tetragonal (BCT) structure. There is no thermal activation energy for the transformation from austenite to martensite. There is no compositional change so the atoms generally retain their same neighbours. Martensite has a lower density (it expands during the cooling) than does austenite, so that the transformation between them results in
1088-512: A geographical frame of reference. Of these, 38 developed gradually since the Middle Ages ; these were reformed to 51 in 1974 and to their current number in 1996. Each has a Lord Lieutenant and High Sheriff ; these posts are used to represent the British monarch locally. Some counties, such as Herefordshire , are only divided further into civil parishes. The royal county of Berkshire and
1224-583: A hard oxide forms on the metal surface; this is known as stainless steel . Tungsten slows the formation of cementite , keeping carbon in the iron matrix and allowing martensite to preferentially form at slower quench rates, resulting in high-speed steel . The addition of lead and sulphur decrease grain size, thereby making the steel easier to turn , but also more brittle and prone to corrosion. Such alloys are nevertheless frequently used for components such as nuts, bolts, and washers in applications where toughness and corrosion resistance are not paramount. For
1360-445: A hard but brittle martensitic structure. The steel is then tempered, which is just a specialized type of annealing, to reduce brittleness. In this application the annealing (tempering) process transforms some of the martensite into cementite, or spheroidite and hence it reduces the internal stresses and defects. The result is a more ductile and fracture-resistant steel. When iron is smelted from its ore, it contains more carbon than
1496-434: A higher than 2.1% carbon content are known as cast iron . With modern steelmaking techniques such as powder metal forming, it is possible to make very high-carbon (and other alloy material) steels, but such are not common. Cast iron is not malleable even when hot, but it can be formed by casting as it has a lower melting point than steel and good castability properties. Certain compositions of cast iron, while retaining

Subsequently, the House of Plantagenet from Anjou inherited the English throne under Henry II , adding England to the budding Angevin Empire of fiefs the family had inherited in France including Aquitaine . They reigned for three centuries, some noted monarchs being Richard I , Edward I , Edward III and Henry V . The period saw changes in trade and legislation, including
2040-796: A separate sovereign state on 1 May 1707, when the Acts of Union brought into effect a political union with the Kingdom of Scotland that created the Kingdom of Great Britain . England is the origin of the English language , the English legal system (which served as the basis for the common law systems of many other countries), association football , and the Anglican branch of Christianity; its parliamentary system of government has been widely adopted by other nations. The Industrial Revolution began in 18th-century England, transforming its society into
2176-534: A small concentration of carbon, no more than 0.005% at 0 °C (32 °F) and 0.021 wt% at 723 °C (1,333 °F). The inclusion of carbon in alpha iron is called ferrite . At 910 °C, pure iron transforms into a face-centred cubic (FCC) structure, called gamma iron or γ-iron. The inclusion of carbon in gamma iron is called austenite. The more open FCC structure of austenite can dissolve considerably more carbon, as much as 2.1%, (38 times that of ferrite) carbon at 1,148 °C (2,098 °F), which reflects
2312-453: A steel's final rolling, it is heat treated for strength; however, this is relatively rare. Steel was known in antiquity and was produced in bloomeries and crucibles . The earliest known production of steel is seen in pieces of ironware excavated from an archaeological site in Anatolia ( Kaman-Kalehöyük ) which are nearly 4,000 years old, dating from 1800 BC. Wootz steel
2448-450: A struggle for hegemony between Northumbria and Mercia, which in the 8th century gave way to Mercian preeminence. In the early 9th century Mercia was displaced as the foremost kingdom by Wessex. Later in that century escalating attacks by the Danes culminated in the conquest of the north and east of England, overthrowing the kingdoms of Northumbria, Mercia and East Anglia. Wessex under Alfred
2584-477: A subsequent step. Other materials are often added to the iron/carbon mixture to produce steel with the desired properties. Nickel and manganese in steel add to its tensile strength and make the austenite form of the iron-carbon solution more stable, chromium increases hardness and melting temperature, and vanadium also increases hardness while making it less prone to metal fatigue . To inhibit corrosion, at least 11% chromium can be added to steel so that
2720-672: Is continuously cast into long slabs, cut and shaped into bars and extrusions and heat treated to produce a final product. Today, approximately 96% of steel is continuously cast, while only 4% is produced as ingots. The ingots are then heated in a soaking pit and hot rolled into slabs, billets , or blooms . Slabs are hot or cold rolled into sheet metal or plates. Billets are hot or cold rolled into bars, rods, and wire. Blooms are hot or cold rolled into structural steel , such as I-beams and rails . In modern steel mills these processes often occur in one assembly line , with ore coming in and finished steel products coming out. Sometimes after
2856-467: Is also applied to England in a more poetic capacity, though its original meaning is the island of Britain as a whole. The earliest known evidence of human presence in the area now known as England was that of Homo antecessor , dating to about 780,000 years ago. The oldest proto-human bones discovered in England date from 500,000 years ago. Modern humans are known to have inhabited the area during

#17327795444542992-636: Is also very reusable: it is one of the world's most-recycled materials, with a recycling rate of over 60% globally . The noun steel originates from the Proto-Germanic adjective * * stahliją or * * stakhlijan 'made of steel', which is related to * * stahlaz or * * stahliją 'standing firm'. The carbon content of steel is between 0.02% and 2.14% by weight for plain carbon steel ( iron - carbon alloys ). Too little carbon content leaves (pure) iron quite soft, ductile, and weak. Carbon contents higher than those of steel make

Stainless steels , which are resistant to corrosion and oxidation , typically need an additional 11% chromium . Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic . The interaction of the allotropes of iron with
3264-403: Is common for quench cracks to form when steel is water quenched, although they may not always be visible. There are many types of heat treating processes available to steel. The most common are annealing , quenching , and tempering . Annealing is the process of heating the steel to a sufficiently high temperature to relieve local internal stresses. It does not create a general softening of

Months with mild to warm weather are May, June, September and October. Rainfall is spread fairly evenly throughout the year. Important influences on the climate of England are its proximity to the Atlantic Ocean , its northern latitude and
3536-403: Is desirable. To become steel, it must be reprocessed to reduce the carbon to the correct amount, at which point other elements can be added. In the past, steel facilities would cast the raw steel product into ingots which would be stored until use in further refinement processes that resulted in the finished product. In modern facilities, the initial product is close to the final composition and
3672-405: Is extracted from iron ore by removing the oxygen through its combination with a preferred chemical partner such as carbon which is then lost to the atmosphere as carbon dioxide. This process, known as smelting , was first applied to metals with lower melting points, such as tin , which melts at about 250 °C (482 °F), and copper , which melts at about 1,100 °C (2,010 °F), and
3808-641: Is governed directly by the Parliament of the United Kingdom , although other countries of the United Kingdom have devolved governments. There has been debate about how to counterbalance this in England. Originally it was planned that various regions of England would be devolved, but following the proposal's rejection by the North East in a 2004 referendum , this has not been carried out. In 2024, an England-only intergovernmental body, known as
3944-408: Is heat treated to contain both a ferritic and martensitic microstructure to produce a formable, high strength steel. Transformation Induced Plasticity (TRIP) steel involves special alloying and heat treatments to stabilize amounts of austenite at room temperature in normally austenite-free low-alloy ferritic steels. By applying strain, the austenite undergoes a phase transition to martensite without

Basic oxygen steelmaking is superior to previous steelmaking methods because the oxygen pumped into the furnace limited impurities, primarily nitrogen, that previously had entered from the air used, and because, with respect to the open hearth process, the same quantity of steel from
10336-547: The North, and the successful Norman Conquest in October 1066, accomplished by an army led by Duke William of Normandy invading at Hastings late September 1066. The Normans themselves originated from Scandinavia and had settled in Normandy in the late 9th and early 10th centuries. This conquest led to the almost total dispossession of the English elite and its replacement by a new French-speaking aristocracy, whose speech had
10472-682: The Pope. During the 14th century, the Plantagenets and the House of Valois claimed to be legitimate claimants to the House of Capet and of France; the two powers clashed in the Hundred Years' War . The Black Death epidemic hit England ; starting in 1348, it eventually killed up to half of England's inhabitants . Between 1453 and 1487, a civil war known as the War of the Roses waged between
10608-1015: The Royal Society and other English initiatives combined with the Scottish Enlightenment to create innovations in science and engineering, while the enormous growth in British overseas trade protected by the Royal Navy paved the way for the establishment of the British Empire . Domestically it drove the Industrial Revolution , a period of profound change in the socioeconomic and cultural conditions of England, resulting in industrialised agriculture, manufacture, engineering and mining, as well as new and pioneering road, rail and water networks to facilitate their expansion and development. The opening of Northwest England's Bridgewater Canal in 1761 ushered in
10744-432: The United Kingdom has moved towards devolved governance in Scotland, Wales and Northern Ireland. England and Wales continues to exist as a jurisdiction within the United Kingdom. Devolution has stimulated a greater emphasis on a more English-specific identity and patriotism. There is no devolved English government, but an attempt to create a similar system on a sub-regional basis was rejected by referendum . England
10880-607: The United Kingdom as part of the Allies . Two decades later, in World War II , the United Kingdom was again one of the Allies . Developments in warfare technology saw many cities damaged by air-raids during the Blitz . Following the war, the British Empire experienced rapid decolonisation , and there was a speeding-up of technological innovations; automobiles became the primary means of transport and Frank Whittle 's development of
11016-619: The addition of heat. Twinning Induced Plasticity (TWIP) steel uses a specific type of strain to increase the effectiveness of work hardening on the alloy. England – in Europe (green & dark grey) – in the United Kingdom (green) England is a country that is part of the United Kingdom . It is located on the island of Great Britain , of which it covers about 62%, and more than 100 smaller adjacent islands . It has land borders with Scotland to
11152-401: The alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile , or soft and easily formed. In steel, small amounts of carbon, other elements, and inclusions within the iron act as hardening agents that prevent
11288-577: The area, the Beaker culture people made bronze , and later iron from iron ores. The development of iron smelting allowed the construction of better ploughs , advancing agriculture (for instance, with Celtic fields ), as well as the production of more effective weapons. During the Iron Age , Celtic culture , deriving from the Hallstatt and La Tène cultures , arrived from Central Europe. Brythonic
11424-767: The auspices of James VI and I the Authorised King James Version of the Holy Bible was published in 1611. It was the standard version of the Bible read by most Protestant Christians for four hundred years until modern revisions were produced in the 20th century. Based on conflicting political, religious and social positions, the English Civil War was fought between the supporters of Parliament and those of King Charles I , known colloquially as Roundheads and Cavaliers respectively. This
11560-436: The austenite grain boundaries until the percentage of carbon in the grains has decreased to the eutectoid composition (0.8% carbon), at which point the pearlite structure forms. For steels that have less than 0.8% carbon (hypoeutectoid), ferrite will first form within the grains until the remaining composition rises to 0.8% of carbon, at which point the pearlite structure will form. No large inclusions of cementite will form at
11696-471: The austenite is for it to precipitate out of solution as cementite , leaving behind a surrounding phase of BCC iron called ferrite with a small percentage of carbon in solution. The two, cementite and ferrite, precipitate simultaneously producing a layered structure called pearlite , named for its resemblance to mother of pearl . In a hypereutectoid composition (greater than 0.8% carbon), the carbon will first precipitate out as large inclusions of cementite at
11832-494: The boundaries in hypoeutectoid steel. The above assumes that the cooling process is very slow, allowing enough time for the carbon to migrate. As the rate of cooling is increased the carbon will have less time to migrate to form carbide at the grain boundaries but will have increasingly large amounts of pearlite of a finer and finer structure within the grains; hence the carbide is more widely dispersed and acts to prevent slip of defects within those grains, resulting in hardening of
11968-455: The combination, bronze, which has a melting point lower than 1,083 °C (1,981 °F). In comparison, cast iron melts at about 1,375 °C (2,507 °F). Small quantities of iron were smelted in ancient times, in the solid-state, by heating the ore in a charcoal fire and then welding the clumps together with a hammer and in the process squeezing out the impurities. With care, the carbon content could be controlled by moving it around in
12104-585: The conquered territories by Anglo-Saxon paganism , but was reintroduced by missionaries from Rome led by Augustine from 597. Disputes between the Roman- and Celtic-dominated forms of Christianity ended in victory for the Roman tradition at the Council of Whitby (664), which was ostensibly about tonsures (clerical haircuts) and the date of Easter, but more significantly, about the differences in Roman and Celtic forms of authority, theology, and practice. During
12240-541: The conquest of this united kingdom by Sweyn Forkbeard in 1013 and again by his son Cnut in 1016, turning it into the centre of a short-lived North Sea Empire that also included Denmark and Norway . However, the native royal dynasty was restored with the accession of Edward the Confessor in 1042. A dispute over the succession to Edward led to an unsuccessful Norwegian Invasion in September 1066 close to York in
12376-454: The course of the fifth and sixth centuries, initially in the eastern part of the country. Their advance was contained for some decades after the Britons' victory at the Battle of Mount Badon , but subsequently resumed, overrunning the fertile lowlands of Britain and reducing the area under Brittonic control to a series of separate enclaves in the more rugged country to the west by the end of
12512-883: The custom of calling the Germanic people in Britain Angli Saxones or English Saxons to distinguish them from continental Saxons (Eald-Seaxe) of Old Saxony in Germany. In Scottish Gaelic , the Saxon tribe gave their name to the word for England ( Sasunn ); similarly, the Welsh name for the English language is Saesneg . A romantic name for England is Loegria , related to the Welsh word for England, Lloegr , and made popular by its use in Arthurian legend . Albion
12648-637: The early 2010s England was divided for a few purposes into regions; a 1998 referendum for the London Region created the London Assembly two years later. A failed 2004 North East England devolution referendum cancelled further regional assembly devolution with the regional structure outside London abolished. Ceremonially and administratively, the region is divided between the City of London and Greater London ; these are further divided into
12784-452: The economies of melting and casting, can be heat treated after casting to make malleable iron or ductile iron objects. Steel is distinguishable from wrought iron (now largely obsolete), which may contain a small amount of carbon but large amounts of slag . Iron is commonly found in the Earth's crust in the form of an ore , usually an iron oxide, such as magnetite or hematite . Iron
12920-596: The finest steel in the world exported to the Roman, Egyptian, Chinese and Arab worlds at that time – what they called Seric Iron . A 200 BC Tamil trade guild in Tissamaharama , in the South East of Sri Lanka, brought with them some of the oldest iron and steel artifacts and production processes to the island from the classical period . The Chinese and locals in Anuradhapura , Sri Lanka had also adopted
13056-579: The fire. Unlike copper and tin, liquid or solid iron dissolves carbon quite readily. All of these temperatures could be reached with ancient methods used since the Bronze Age . Since the oxidation rate of iron increases rapidly beyond 800 °C (1,470 °F), it is important that smelting take place in a low-oxygen environment. Smelting, using carbon to reduce iron oxides, results in an alloy ( pig iron ) that retains too much carbon to be called steel. The excess carbon and other impurities are removed in
13192-513: The form of charcoal) in a crucible, was produced in Merv by the 9th to 10th century AD. In the 11th century, there is evidence of the production of steel in Song China using two techniques: a "berganesque" method that produced inferior, inhomogeneous steel, and a precursor to the modern Bessemer process that used partial decarburization via repeated forging under a cold blast . Since
13328-498: The group sold, with consequent savings in jobs. The group was headed by Angad Paul , the son of Lord Paul, from 1996, until his death on 8 November 2015. According to a text published 1995, the Caparo group specialized in take-overs. At the time of publishing, the company had fixed assets and investments (having been quoted), of £26 million. A court case involving Caparo, Caparo Industries plc v Dickman , dated to 1990, has become
13464-599: The hardenability of thick sections. High strength low alloy steel has small additions (usually < 2% by weight) of other elements, typically 1.5% manganese, to provide additional strength for a modest price increase. Recent corporate average fuel economy (CAFE) regulations have given rise to a new variety of steel known as Advanced High Strength Steel (AHSS). This material is both strong and ductile so that vehicle structures can maintain their current safety levels while using less material. There are several commercially available grades of AHSS, such as dual-phase steel , which
13600-538: The hierarchy, which must follow its directions. The Secretary of State for Justice is the minister responsible to Parliament for the judiciary , the court system and prisons and probation in England. Crime increased between 1981 and 1995 but fell by 42% in the period 1995–2006. The prison population doubled over the same period, giving it one of the highest incarceration rates in Western Europe at 147 per 100,000. His Majesty's Prison Service , reporting to
13736-439: The main production route. At the end of 2008, the steel industry faced a sharp downturn that led to many cut-backs. In 2021, it was estimated that around 7% of the global greenhouse gas emissions resulted from the steel industry. Reduction of these emissions are expected to come from a shift in the main production route using cokes, more recycling of steel and the application of carbon capture and storage technology. Steel
13872-453: The metropolitan counties have different types of status to other ceremonial counties. The second tier is made up of combined authorities and the 27 county-tier shire counties . In 1974, all ceremonial counties were two-tier; and with the metropolitan county tier phased out, the 1996 reform separated the ceremonial county and the administrative county tier. England is also divided into local government districts. The district can align to
14008-707: The mid-to-late 17th century, two political factions had emerged – the Tories and Whigs . Though the Tories initially supported Catholic king James II , some of them, along with the Whigs, during the Revolution of 1688 invited the Dutch Prince William of Orange to defeat James and become the king. Some English people, especially in the north, were Jacobites and continued to support James and his sons. Under
14144-569: The monastic community and monastic leaders were more like chieftains, as peers, rather than in the more hierarchical system of the Roman-dominated church. Roman military withdrawals left Britain open to invasion by pagan, seafaring warriors from north-western continental Europe, chiefly the Saxons, Angles , Jutes and Frisians who had long raided the coasts of the Roman province. These groups then began to settle in increasing numbers over
14280-450: The most part, however, p-block elements such as sulphur, nitrogen , phosphorus , and lead are considered contaminants that make steel more brittle and are therefore removed from steel during the melting processing. The density of steel varies based on the alloying constituents but usually ranges between 7,750 and 8,050 kg/m (484 and 503 lb/cu ft), or 7.75 and 8.05 g/cm (4.48 and 4.65 oz/cu in). Even in
14416-446: The movement of dislocations . The carbon in typical steel alloys may contribute up to 2.14% of its weight. Varying the amount of carbon and many other alloying elements, as well as controlling their chemical and physical makeup in the final steel (either as solute elements, or as precipitated phases), impedes the movement of the dislocations that make pure iron ductile, and thus controls and enhances its qualities. These qualities include
14552-611: The nation, many by Natural England themselves, but also by non-governmental organisations, including the members of The Wildlife Trusts partnership, the National Trust , and the Royal Society for the Protection of Birds . There are 221 NNRs in England covering 110,000 hectares (1,100 square kilometres). Often they contain rare species or nationally important populations of plants and animals. . The Environment Agency
14688-588: The north and Wales to the west, and is otherwise surrounded by the North Sea to the east, the English Channel to the south, the Celtic Sea to the south-west, and the Irish Sea to the west. Continental Europe lies to the south-east, and Ireland to the west. At the 2021 census , the population was 56,490,048. London is both the largest city and the capital . The area now called England
14824-613: The north and west of the country. The northern uplands include the Pennines , a chain of uplands dividing east and west, the Lake District mountains in Cumbria, and the Cheviot Hills , straddling the border between England and Scotland. The highest point in England, at 978 metres (3,209 ft), is Scafell Pike in the Lake District. The Shropshire Hills are near Wales while Dartmoor and Exmoor are two upland areas in
14960-449: The product but only locally relieves strains and stresses locked up within the material. Annealing goes through three phases: recovery , recrystallization , and grain growth . The temperature required to anneal a particular steel depends on the type of annealing to be achieved and the alloying constituents. Quenching involves heating the steel to create the austenite phase then quenching it in water or oil . This rapid cooling results in
15096-759: The production methods of creating wootz steel from the Chera Dynasty Tamils of South India by the 5th century AD. In Sri Lanka, this early steel-making method employed a unique wind furnace, driven by the monsoon winds, capable of producing high-carbon steel. Since the technology was acquired from the Tamilians from South India, the origin of steel technology in India can be conservatively estimated at 400–500 BC. The manufacture of wootz steel and Damascus steel , famous for its durability and ability to hold an edge, may have been taken by
15232-426: The quality of the final product. Today more than 1.6 billion tons of steel is produced annually. Modern steel is generally identified by various grades defined by assorted standards organizations . The modern steel industry is one of the largest manufacturing industries in the world, but also one of the most energy and greenhouse gas emission intense industries, contributing 8% of global emissions. However, steel
15368-450: The settlement period the lands ruled by the incomers seem to have been fragmented into numerous tribal territories, but by the 7th century, when substantial evidence of the situation again becomes available, these had coalesced into roughly a dozen kingdoms including Northumbria , Mercia , Wessex , East Anglia , Essex , Kent and Sussex . Over the following centuries, this process of political consolidation continued. The 7th century saw
15504-477: The signing of Magna Carta , an English legal charter used to limit the sovereign's powers by law and protect the privileges of freemen. Catholic monasticism flourished, providing philosophers, and the universities of Oxford and Cambridge were founded with royal patronage. The Principality of Wales became a Plantagenet fief during the 13th century and the Lordship of Ireland was given to the English monarchy by
15640-636: The south-west of the country. The approximate dividing line between terrain types is often indicated by the Tees–Exe line . The Pennines, known as the "backbone of England", are the oldest range of mountains in the country, originating from the end of the Paleozoic Era around 300 million years ago. Their geological composition includes, among others, sandstone and limestone , and also coal. There are karst landscapes in calcite areas such as parts of Yorkshire and Derbyshire . The Pennine landscape
15776-530: The standard in cases where it is necessary to establish negligence . Steel Steel is an alloy of iron and carbon with improved strength and fracture resistance compared to other forms of iron. Because of its high tensile strength and low cost, steel is one of the most commonly manufactured materials in the world. Steel is used in buildings, as concrete reinforcing rods, in bridges, infrastructure, tools, ships, trains, cars, bicycles, machines, electrical appliances, furniture, and weapons. Iron
15912-547: The standing of the British military and navy – was prestigious. Technologically, this era saw many innovations that proved key to the United Kingdom's power and prosperity. Political agitation at home from radicals such as the Chartists and the suffragettes enabled legislative reform and universal suffrage . Power shifts in east-central Europe led to World War I; hundreds of thousands of English soldiers died fighting for
16048-401: The steel. At the very high cooling rates produced by quenching, the carbon has no time to migrate but is locked within the face-centred austenite and forms martensite . Martensite is a highly strained and stressed, supersaturated form of carbon and iron and is exceedingly hard but brittle. Depending on the carbon content, the martensitic phase takes different forms. Below 0.2% carbon, it takes on
16184-561: The steel. The early modern crucible steel industry resulted from the invention of Benjamin Huntsman in the 1740s. Blister steel (made as above) was melted in a crucible or in a furnace, and cast (usually) into ingots. The modern era in steelmaking began with the introduction of Henry Bessemer 's process in 1855, the raw material for which was pig iron. His method let him produce steel in large quantities cheaply, thus mild steel came to be used for most purposes for which wrought iron
16320-561: The technology of that time, such qualities were produced by chance rather than by design. Natural wind was used where the soil containing iron was heated by the use of wood. The ancient Sinhalese managed to extract a ton of steel for every 2 tons of soil, a remarkable feat at the time. One such furnace was found in Samanalawewa and archaeologists were able to produce steel as the ancients did. Crucible steel , formed by slowly heating and cooling pure iron and carbon (typically in
16456-491: The threat: Spain launched two further armadas, in 1596 and 1597 , but both were driven back by storms. The political structure of the island changed in 1603, when the King of Scots , James VI , a kingdom which had been a long-time rival to English interests, inherited the throne of England as James I, thereby creating a personal union . He styled himself King of Great Britain , although this had no basis in English law. Under
16592-803: The two branches of the royal family, the Yorkists and Lancastrians . Eventually it led to the Yorkists losing the throne entirely to a Welsh noble family the Tudors , a branch of the Lancastrians headed by Henry Tudor who invaded with Welsh and Breton mercenaries, gaining victory at the Battle of Bosworth Field where the Yorkist king Richard III was killed. During the Tudor period , England began to develop naval skills , and exploration intensified in
16728-525: The upper carbon content of steel, beyond which is cast iron. When carbon moves out of solution with iron, it forms a very hard, but brittle material called cementite (Fe 3 C). When steels with exactly 0.8% carbon (known as a eutectoid steel), are cooled, the austenitic phase (FCC) of the mixture attempts to revert to the ferrite phase (BCC). The carbon no longer fits within the FCC austenite structure, resulting in an excess of carbon. One way for carbon to leave
16864-541: The warming of the sea by the Gulf Stream . Rainfall is higher in the west, and parts of the Lake District receive more rain than anywhere else in the country. Since weather records began, the highest temperature recorded was 40.3 °C (104.5 °F) on 19 July 2022 at Coningsby , Lincolnshire , while the lowest was −26.1 °C (−15.0 °F) on 10 January 1982 in Edgmond , Shropshire. The fauna of England
17000-550: The world's first industrialised nation. England is home to the two oldest universities in the English-speaking world: the University of Oxford , founded in 1096, and the University of Cambridge , founded in 1209. Both universities are ranked among the most prestigious in the world. England's terrain chiefly consists of low hills and plains , especially in the centre and south . Upland and mountainous terrain
17136-576: Was an interwoven part of the wider multifaceted Wars of the Three Kingdoms , involving Scotland and Ireland . The Parliamentarians were victorious, Charles I was executed and the kingdom replaced by the Commonwealth . Leader of the Parliament forces, Oliver Cromwell declared himself Lord Protector in 1653; a period of personal rule followed. After Cromwell's death and the resignation of his son Richard as Lord Protector, Charles II
17272-718: Was developed in Southern India and Sri Lanka in the 1st millennium BCE. Metal production sites in Sri Lanka employed wind furnaces driven by the monsoon winds, capable of producing high-carbon steel. Large-scale wootz steel production in India using crucibles occurred by the sixth century BC, the pioneering precursor to modern steel production and metallurgy. High-carbon steel was produced in Britain at Broxmouth Hillfort from 490–375 BC, and ultrahigh-carbon steel
17408-401: Was established with the Bill of Rights in 1689. Among the statutes set down were that the law could only be made by Parliament and could not be suspended by the King, also that the King could not impose taxes or raise an army without the prior approval of Parliament. Also since that time, no British monarch has entered the House of Commons when it is sitting, which is annually commemorated at
17544-428: Was first inhabited by modern humans during the Upper Paleolithic . It takes its name from the Angles , a Germanic tribe who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had extensive cultural and legal impact on the wider world since the Age of Discovery , which began during the 15th century. The Kingdom of England , which included Wales after 1535, ceased to be
17680-446: Was formerly used. The Gilchrist-Thomas process (or basic Bessemer process ) was an improvement to the Bessemer process, made by lining the converter with a basic material to remove phosphorus. Another 19th-century steelmaking process was the Siemens-Martin process , which complemented the Bessemer process. It consisted of co-melting bar iron (or steel scrap) with pig iron. These methods of steel production were rendered obsolete by
17816-399: Was invited to return as monarch in 1660, in a move called the Restoration . With the reopening of theatres, fine arts, literature and performing arts flourished throughout the Restoration of the "Merry Monarch" Charles II. After the Glorious Revolution of 1688, it was constitutionally established that King and Parliament should rule together, though Parliament would have the real power. This
17952-572: Was lower than the present day and Britain was connected by land bridge to Ireland and Eurasia . As the seas rose, it was separated from Ireland 10,000 years ago and from Eurasia two millennia later. The Beaker culture arrived around 2,500 BC, introducing drinking and food vessels constructed from clay, as well as vessels used as reduction pots to smelt copper ores. It was during this time that major Neolithic monuments such as Stonehenge (phase III) and Avebury were constructed. By heating together tin and copper, which were in abundance in
18088-438: Was produced globally, with 630,000,000 tonnes (620,000,000 long tons; 690,000,000 short tons) recycled. Modern steels are made with varying combinations of alloy metals to fulfil many purposes. Carbon steel , composed simply of iron and carbon, accounts for 90% of steel production. Low alloy steel is alloyed with other elements, usually molybdenum , manganese, chromium, or nickel, in amounts of up to 10% by weight to improve
18224-469: Was produced in the Netherlands from the 2nd-4th centuries AD. The Roman author Horace identifies steel weapons such as the falcata in the Iberian Peninsula , while Noric steel was used by the Roman military . The Chinese of the Warring States period (403–221 BC) had quench-hardened steel, while Chinese of the Han dynasty (202 BC—AD 220) created steel by melting together wrought iron with cast iron, thus producing
18360-568: Was subsequently proclaimed emperor a century later. There is debate about when Christianity was first introduced; it was no later than the 4th century, probably much earlier. According to Bede , missionaries were sent from Rome by Eleutherius at the request of the chieftain Lucius of Britain in 180 AD, to settle differences as to Eastern and Western ceremonials, which were disturbing the church. There are traditions linked to Glastonbury claiming an introduction through Joseph of Arimathea , while others claim through Lucius of Britain. By 410, during
18496-401: Was the spoken language during this time. Society was tribal; according to Ptolemy 's Geographia there were around 20 tribes in the area. Like other regions on the edge of the Empire, Britain had long enjoyed trading links with the Romans. Julius Caesar of the Roman Republic attempted to invade twice in 55 BC; although largely unsuccessful, he managed to set up a client king from
