SAE 304 stainless steel is the most common stainless steel . It is an alloy of iron , carbon , chromium and nickel . It is an austenitic stainless steel , and is therefore not magnetic. It is less electrically and thermally conductive than carbon steel . It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes.

74-499: The composition was developed by W. H. Hatfield at Firth Brown in 1924 and was marketed under the trade name "Staybrite 18/8". It is specified by SAE International as part of its SAE steel grades . It is also known as: 304 stainless steel has excellent resistance to a wide range of atmospheric environments and many corrosive media. It is subject to pitting and crevice corrosion in warm chloride environments and to stress corrosion cracking above about 60 °C (140 °F). It

Although the Roman Empire incorporated peoples from far and wide, genetic studies suggest the Romans did not significantly mix into the British population. The exact nature of

222-717: A common ancestry, history, and culture. The English identity began with the Anglo-Saxons , when they were known as the Angelcynn , meaning race or tribe of the Angles . Their ethnonym is derived from the Angles, one of the Germanic peoples who invaded Britain around the 5th century AD. The English largely descend from two main historical population groups: the West Germanic tribes, including

296-627: A geographic area brings protests, especially from the Scotch . However, although Taylor believed this blurring effect was dying out, in his book The Isles: A History (1999), Norman Davies lists numerous examples in history books of "British" still being used to mean "English" and vice versa. In December 2010, Matthew Parris in The Spectator , analysing the use of "English" over "British", argued that English identity, rather than growing, had existed all along but has recently been unmasked from behind

370-697: A greater extent than their white counterparts; however, groups such as the Campaign for an English Parliament (CEP) suggest the emergence of a broader civic and multi-ethnic English nationhood. Scholars and journalists have noted a rise in English self-consciousness, with increased use of the English flag , particularly at football matches where the Union flag was previously more commonly flown by fans. This perceived rise in English self-consciousness has generally been attributed to

444-450: A large statistical spread in all cases. However, the authors noted that the similarity observed between the various sample groups was likely to be due to more recent internal migration. Another 2016 study conducted using evidence from burials found in northern England, found that a significant genetic difference was present in bodies from the Iron Age and the Roman period on the one hand, and

518-457: A majority of respondents thought that being English was not dependent on race. 77% of white respondents in England agreed that "Being English is open to people of different ethnic backgrounds who identify as English", whereas 14% were of the view that "Only people who are white count as truly English". Amongst ethnic minority respondents, the equivalent figures were 68% and 19%. Research has found that

592-597: A native British "North Atlantic" population and a Danish-like population. While much of the latter signature was attributed to the earlier settlement of the Anglo-Saxons, it was calculated that up to 6% of it could have come from Danish Vikings, with a further 4% contribution from a Norwegian-like source representing the Norwegian Vikings. The study also found an average 18% admixture from a source further south in Europe, which

666-402: A parliament being established. Krishan Kumar notes that support for measures to ensure that only English MPs can vote on legislation that applies only to England is generally higher than that for the establishment of an English parliament, although support for both varies depending on the timing of the opinion poll and the wording of the question. Electoral support for English nationalist parties

740-463: A rise in English self-awareness. This is linked to the expressions of national self-awareness of the other British nations of Wales, Scotland and, to some extent, Northern Ireland which take their most solid form in the new devolved political arrangements within the United Kingdom ;– and the waning of a shared British national identity with the growing distance between the end of

814-627: A separate ethnic identity, others have assimilated and intermarried with the English. Since Oliver Cromwell 's resettlement of the Jews in 1656, there have been waves of Jewish immigration from Russia in the 19th century and from Germany in the 20th. After the French king Louis XIV declared Protestantism illegal in 1685 in the Edict of Fontainebleau , an estimated 50,000 Protestant Huguenots fled to England. Due to sustained and sometimes mass emigration of

888-651: A separate people from the English. This separation was enshrined when Alfred the Great signed the Treaty of Alfred and Guthrum to establish the Danelaw, a division of England between English and Danish rule, with the Danes occupying northern and eastern England. However, Alfred's successors subsequently won military victories against the Danes, incorporating much of the Danelaw into the nascent kingdom of England. Danish invasions continued into

962-402: A strong influence on room temperature strength and thus the specified minimum tensile properties of 304L are 34 MPa (5,000 psi) lower than for 304. However, nitrogen also has a strong influence on room temperature strength and a tiny addition of nitrogen produces 304L with the same tensile strength as 304. Thus, practically all 304L is produced as dual certified 304/304L, meaning it meets

1036-542: A veneer of Britishness. English people, like most Europeans, largely descend from three distinct lineages: Mesolithic hunter-gatherers , descended from a Cro-Magnon population that arrived in Europe about 45,000 years ago; Neolithic farmers who migrated from Anatolia during the Neolithic Revolution 9,000 years ago; and Yamnaya Steppe pastoralists who expanded into Europe from the Pontic–Caspian steppe in

1110-464: Is also low, even though there is public support for many of the policies they espouse. The English Democrats gained just 64,826 votes in the 2010 UK general election , accounting for 0.3 per cent of all votes cast in England. Kumar argued in 2010 that "despite devolution and occasional bursts of English nationalism – more an expression of exasperation with the Scots or Northern Irish – the English remain on

1184-567: Is also used in the architectural field for exterior accents such as water and fire features. It is also a common coil material for vaporizers. Early SpaceX Starships used SAE 301 stainless steel in their construction, before moving over to SAE 304L for the SN7 test tank and Starship SN8 in 2020. 304 stainless steel was used to clad the Gateway Arch in St. Louis, Missouri. 304, 304H, and 304L all possess

1332-551: Is considered resistant to pitting corrosion in water with up to about 400 mg/L chlorides at ambient temperatures, reducing to about 150 mg/L at 60 °C. 304 stainless steel is also very sensitive at room temperature to the thiosulfate anions released by the oxidation of pyrite (as encountered in acid mine drainage ) and can undergo severe pitting corrosion problems when in close contact with pyrite - or sulfide -rich clay materials exposed to oxidation. For more severe corrosion conditions, when 304 stainless steel

1406-586: Is credited with the invention in 1924 of 18/8 stainless steel (18% chromium, 8% nickel); he also invented 18/8 stainless with titanium added, now known as 321. In 1940 he devised "Rex 78", a stainless steel alloy for use in Frank Whittle 's turbojet engine project, the material being first used in the Power Jets W.1 . He authored a variety of technical papers on metallurgy, with particular reference to rust, acid and heat-resistant steels and cast iron. There

1480-399: Is preferred. Its lack of a minimum carbon content is not ideal for high-temperature applications where optimal strength is required, thus, 304H is usually preferred. Thus 304 is typically restricted to bars that will be machined into components where welding is not required or thin sheets that are formed in articles such as kitchen sinks or cookware that are also not welded. Carbon content has

1554-481: Is restricted to 0.04–0.10%, which provides optimal high-temperature strength. The carbon content of 304L (UNS 30403) is restricted to a maximum of 0.035%, which prevents sensitization during welding. Sensitization is the formation of chromium carbides along grain boundaries when stainless steel is exposed to temperatures in the approximate range of 480–820 °C (900–1,500 °F). The subsequent formation of chromium carbide results in reduced corrosion resistance along

1628-463: Is too sensitive to pitting or crevice corrosion by chlorides or general corrosion in acidic applications, it is commonly replaced by 316 stainless steel. 304 and 302 stainless steels are subject to chloride stress fracture failure when used in tropical salt water conditions such as oil or gas rigs. 316 stainless steel is the preferred alloy for these conditions. 304 stainless steel cannot be heat treated—instead it can be strengthened by cold working. It

1702-612: Is usually termed "elite dominance". The second process is explained through incentives, such as the Wergild outlined in the law code of Ine of Wessex which produced an incentive to become Anglo-Saxon or at least English speaking. Historian Malcolm Todd writes, "It is much more likely that a large proportion of the British population remained in place and was progressively dominated by a Germanic aristocracy, in some cases marrying into it and leaving Celtic names in the, admittedly very dubious, early lists of Anglo-Saxon dynasties. But how we identify

1776-560: Is weakest in the annealed condition, and is strongest in the full-hard condition. The tensile yield strength ranges from 210 to 1,050 MPa (30,000 to 153,000 psi). The density is 7,900 kg/m (0.286 lb/cu in), and its modulus of elasticity ranges from 183 to 200 GPa (26.6 × 10 ^ to 29.0 × 10 ^  psi). 304 stainless steel is used for a variety of household and industrial applications such as food handling and processing equipment, screws, machinery parts, utensils, and exhaust manifolds . 304 stainless steel

1850-487: The Anglo-Saxons , a group of closely related Germanic tribes that began migrating to eastern and southern Britain, from southern Denmark and northern Germany, in the 5th century AD, after the Romans had withdrawn from Britain . The Anglo-Saxons gave their name to England ("Engla land", meaning "Land of the Angles") and to the English. The Anglo-Saxons arrived in a land that was already populated by people commonly referred to as

1924-544: The British Empire and the present. Many recent immigrants to England have assumed a solely British identity, while others have developed dual or mixed identities. Use of the word "English" to describe Britons from ethnic minorities in England is complicated by most non-white people in England identifying as British rather than English. In their 2004 Annual Population Survey , the Office for National Statistics compared

1998-626: The Irish , current estimates indicate that around 6 million people in the UK have at least one grandparent born in the Republic of Ireland. There has been a small black presence in England since the 16th century due to the slave trade , and a small Indian presence since at least the 17th century because of the East India Company and British Raj . Black and Asian populations have only grown throughout

2072-606: The Treaty of Union . The Parliament of Scotland had previously passed its own Act of Union, so the Kingdom of Great Britain was born on 1 May 1707. In 1801, another Act of Union formed a union between the Kingdom of Great Britain and the Kingdom of Ireland , creating the United Kingdom of Great Britain and Ireland . In 1922, about two-thirds of the Irish population (those who lived in 26 of

2146-706: The devolution in the late 1990s of some powers to the Scottish Parliament and National Assembly for Wales . In policy areas for which the devolved administrations in Scotland, Wales and Northern Ireland have responsibility, the UK Parliament votes on laws that consequently only apply to England. Because the Westminster Parliament is composed of MPs from throughout the United Kingdom, this has given rise to

2220-464: The " Romano-British "—the descendants of the native Brittonic-speaking population that lived in the area of Britain under Roman rule during the 1st–5th centuries AD. The multi-ethnic nature of the Roman Empire meant that small numbers of other peoples may have also been present in England before the Anglo-Saxons arrived. There is archaeological evidence, for example, of an early North African presence in

2294-462: The " West Lothian question ", a reference to the situation in which MPs representing constituencies outside England can vote on matters affecting only England, but MPs cannot vote on the same matters in relation to the other parts of the UK. Consequently, groups such as the CEP have called for the creation of a devolved English Parliament , claiming that there is now a discriminatory democratic deficit against

2368-552: The 11th century, and there were both English and Danish kings in the period following the unification of England (for example, Æthelred II (978–1013 and 1014–1016) was English but Cnut (1016–1035) was Danish). Gradually, the Danes in England came to be seen as 'English'. They had a noticeable impact on the English language: many English words, such as anger , ball , egg , got , knife , take , and they , are of Old Norse origin , and place names that end in -thwaite and -by are Scandinavian in origin. The English population

The remainder became the United Kingdom of Great Britain and Northern Ireland, although this name was not introduced until 1927, after some years in which the term "United Kingdom" had been little used. Throughout the history of the UK, the English have been dominant in population and in political weight. As a consequence, notions of 'Englishness' and 'Britishness' are often very similar. At

Collectively known as the Anglo-Saxons , they founded what was to become the Kingdom of England by the 10th century, in response to the invasion and extensive settlement of Danes and other Norsemen that began in

2590-522: The Anglo-Saxon period on the other. Samples from modern-day Wales were found to be similar to those from the Iron Age and Roman burials, while samples from much of modern England, East Anglia in particular, were closer to the Anglo-Saxon-era burial. This was found to demonstrate a "profound impact" from the Anglo-Saxon migrations on the modern English gene pool, though no specific percentages were given in

2664-466: The English language became more important even in the court, and the Normans were gradually assimilated, until, by the 14th century, both rulers and subjects regarded themselves as English and spoke the English language. Despite the assimilation of the Normans, the distinction between 'English' and 'French' people survived in some official documents long after it had fallen out of common use, in particular in

2738-578: The English. The establishment of an English parliament has also been backed by a number of Scottish and Welsh nationalists. Writer Paul Johnson has suggested that like most dominant groups, the English have only demonstrated interest in their ethnic self-definition when they were feeling oppressed. John Curtice argues that "In the early years of devolution...there was little sign" of an English backlash against devolution for Scotland and Wales, but that more recently survey data shows tentative signs of "a form of English nationalism...beginning to emerge among

It is currently unknown whether these Beaker peoples went on to develop Celtic languages in the British Isles , or whether later Celtic migrations introduced Celtic languages to Britain. The close genetic affinity of these Beaker people to Continental North Europeans means that British and Irish populations cluster genetically very closely with other Northwest European populations, regardless of how much Anglo-Saxon and Viking ancestry

3108-415: The UK. In his study of English identity, Krishan Kumar describes a common slip of the tongue in which people say "English, I mean British". He notes that this slip is normally made only by the English themselves and by foreigners: "Non-English members of the United Kingdom rarely say 'British' when they mean 'English ' ". Kumar suggests that although this blurring is a sign of England's dominant position with

3182-539: The United Kingdom . The majority of people living in England are British citizens. In the Acts of Union 1707 , the Kingdom of England and the Kingdom of Scotland merged to become the Kingdom of Great Britain . Over the years, English customs and identity have become fairly closely aligned with British customs and identity in general. The demonyms for men and women from England are Englishman and Englishwoman. England itself has no devolved government. The 1990s witnessed

3256-575: The United Kingdom. Wales was annexed by England by the Laws in Wales Acts 1535–1542 , which incorporated Wales into the English state. A new British identity was subsequently developed when James VI of Scotland became James I of England as well, and expressed the desire to be known as the monarch of Britain. In 1707, England formed a union with Scotland by passing an Act of Union in March 1707 that ratified

3330-583: The United States, Canada, Australia, South Africa and New Zealand. In the 2020 United States census , English Americans were the largest group in the United States with 46.5 million Americans self-identifying as having some English origins (many combined with another heritage) representing (19.8%) of the White American population. This includes 25.5 million (12.5%) who were "English alone" - one origin. However, demographers regard this as an undercount, as

3404-474: The arrival of the Anglo-Saxons and their relationship with the Romano-British is a matter of debate. The traditional view is that a mass invasion by various Anglo-Saxon tribes largely displaced the indigenous British population in southern and eastern Britain (modern-day England with the exception of Cornwall ). This is supported by the writings of Gildas , who gives the only contemporary historical account of

3478-561: The cases of eastern regions such as East Anglia and Lincolnshire, while in parts of Northumbria, much of the native population likely remained in place as the incomers took over as elites. In a study of place names in northeastern England and southern Scotland, Bethany Fox found that the migrants settled in large numbers in river valleys, such as those of the Tyne and the Tweed, with the Britons moving to

3552-472: The complex nature of national identities, with many people considering themselves both English and British. A 2017 survey by YouGov found that 38% of English voters considered themselves both English and British, alongside 19% who felt English but not British. Recent surveys of public opinion on the establishment of an English parliament have given widely varying conclusions. In the first five years of devolution for Scotland and Wales, support in England for

3626-585: The context of Indo-European migrations 5,000 years ago. Recent genetic studies have suggested that Britain's Neolithic population was largely replaced by a population from North Continental Europe characterised by the Bell Beaker culture around 2400 BC, associated with the Yamnaya people from the Pontic-Caspian Steppe . This population lacked genetic affinity to some other Bell Beaker populations, such as

3700-602: The death of King Stephen in 1154, when the succession passed to Henry II , House of Plantagenet (based in France), and England became part of the Angevin Empire until its collapse in 1214. Anglo-Norman and Latin continued to be the two languages used officially by the Plantagenet kings until Edward I came to the throne, when Middle English became used in official documents, but alongside Anglo-Norman and Latin. Over time

3774-544: The establishment of an English parliament was low at between 16 and 19%, according to successive British Social Attitudes Surveys . A report, also based on the British Social Attitudes Survey, published in December 2010 suggests that only 29% of people in England support the establishment of an English parliament, though this figure had risen from 17% in 2007. One 2007 poll carried out for BBC Newsnight , however, found that 61 per cent would support such

They found that while 58% of white people in England described their nationality as "English", non-white people were more likely to describe themselves as "British". It is unclear how many British people consider themselves English. The words "English" and "British" are often incorrectly used interchangeably, especially outside

3922-449: The general public". Michael Kenny, Richard English and Richard Hayton, meanwhile, argue that the resurgence in English nationalism predates devolution, being observable in the early 1990s, but that this resurgence does not necessarily have negative implications for the perception of the UK as a political union. Others question whether devolution has led to a rise in English national identity at all, arguing that survey data fails to portray

3996-453: The grain boundary leaving the stainless steel susceptible to unanticipated corrosion in an environment where 304 would be expected to be corrosion resistant. This grain boundary corrosive attack is known as intergranular corrosion. The carbon content of 304 (UNS 30400) is restricted to a maximum of 0.08% and is not useful for corrosive applications where welding is required, such as tanks and pipes where corrosive solutions are involved, and 304L

4070-515: The index of inconsistency is high, and many, if not most, people from English stock have a tendency (since the introduction of a new 'American' category and ignoring the ancestry question in the 2000 census) to identify as simply Americans or if of mixed European ancestry, identify with a more recent and differentiated ethnic group. Prior to this, in the 2000 census , 24,509,692 Americans described their ancestry as wholly or partly English. In addition, 1,035,133 recorded British ancestry. This

This was followed by the Norman Conquest and limited settlement of Normans in England in the late 11th century and a sizeable number of French Protestants who emigrated between the 16th and 18th centuries. Some definitions of English people include, while others exclude, people descended from later migration into England. England is the largest and most populous country of

At first, the Vikings were very much considered

William Herbert Hatfield William Herbert Hatfield (10 April 1882 – 16 October 1943) was an English metallurgist who contributed to the development of stainless steel . Hatfield was born in Sheffield on 10 April 1882 and studied metallurgy at University College, Sheffield , being awarded

4440-553: The new French-speaking Norman elite almost universally replaced the Anglo-Saxon aristocracy and church leaders. After the conquest, "English" normally included all natives of England, whether they were of Anglo-Saxon, Scandinavian or Celtic ancestry, to distinguish them from the Norman invaders, who were regarded as "Norman" even if born in England, for a generation or two after the Conquest. The Norman dynasty ruled England for 87 years until

Similarly, the census of the Republic of Ireland does not collect information on ethnicity, but it does record that there are over 200,000 people living in Ireland who were born in England and Wales . English ethnic descent and emigrant communities are found primarily in the Western world , and settled in significant numbers in some areas. Substantial populations descended from English colonists and immigrants exist in

England has been the destination of varied numbers of migrants at different periods from the 17th century onwards. While some members of these groups seek to practise a form of pluralism, attempting to maintain

4958-567: The study. A third study combined the ancient data from both of the preceding studies and compared it to a large number of modern samples from across Britain and Ireland. This study found that modern southern, central and eastern English populations were of "a predominantly Anglo-Saxon-like ancestry" while those from northern and southwestern England had a greater degree of indigenous origin. A major 2020 study, which used DNA from Viking-era burials in various regions across Europe, found that modern English samples showed nearly equal contributions from

5032-541: The surviving Britons in areas of predominantly Anglo-Saxon settlement, either archaeologically or linguistically, is still one of the deepest problems of early English history." An emerging view is that the degree of population replacement by the Anglo-Saxons, and thus the degree of survival of the Romano-Britons, varied across England, and that as such the overall settlement of Britain by the Anglo-Saxons cannot be described by any one process in particular. Large-scale migration and population shift seems to be most applicable in

The nation of England was formed in 12 July 927 by Æthelstan of Wessex after the Treaty of Eamont Bridge , as Wessex grew from a relatively small kingdom in the South West to become the founder of the Kingdom of the English, incorporating all Anglo-Saxon kingdoms and the Danelaw. The Norman conquest of England during 1066 brought Anglo-Saxon and Danish rule of England to an end, as

A landmark 2022 study titled "The Anglo-Saxon migration and the formation of the early English gene pool", found the English to be of plurality Anglo-Saxon-like ancestry, with heavy native Celtic Briton , and newly confirmed medieval French admixture. Significant regional variation was also observed. The first people to be called "English" were

The influence of later invasions and migrations on the English population has been debated, as studies that sampled only modern DNA have produced uncertain results and have thus been subject to a large variety of interpretations. More recently, however, ancient DNA has been used to provide a clearer picture of the genetic effects of these movements of people.
