Editing Stainless steel (section)

===Rustless steel===
Brearley initially called his new alloy "rustless steel". The alloy was sold in the US under different brand names like "Allegheny metal" and "Nirosta steel". Even within the metallurgy industry, the name remained unsettled; in 1921, one trade journal called it "unstainable steel".<ref>{{cite news |last=Moneypenny |first=J. H.

Brearley worked with a local cutlery manufacturer, who gave it the name "stainless steel".<ref>{{cite web |title=The development of stainless steel |publisher=Korea Iron & Steel Association |work=Stainless Steel Club |location=[[Seoul, Korea]] |url=http://www.stainlesssteel.or.kr/english/stsinfo/develop.asp  |archive-url=https://web.archive.org/web/20050827005100/http://www.stainlesssteel.or.kr/english/stsinfo/develop.asp |archive-date=27 August 2005 |access-date=22 July 2011}}</ref> As late as 1932, [[Ford Motor Company]] continued calling the alloy "rustless steel" in automobile promotional materials.<ref>{{cite web |title=1932 – The Invention of the Ford V8 Engine |date=18 November 2015 |publisher=[[YouTube]] |url=https://www.youtube.com/watch?v=3RB3z1er9Sw |accessdate=5 February 2022}}</ref> However, stainless tended to predominate worldwide, and even in present-day Japan, Western cutlery is simply referred to as "stainless (without the steel) spoon/fork" etc. [ステンレス: sutenresu].

In 1929, before the Great Depression, over 25,000 tons of stainless steel were manufactured and sold in the US annually.<ref>{{cite magazine |title=New Steel Alloy is Rustproof |magazine=Popular Science |url=https://books.google.com/books?id=sygDAAAAMBAJ&pg=PA31 |date=December 1930 |publisher=Bonnier Corporation |pages=31– |issn=0161-7370 |access-date=1 October 2021 |archive-date=13 April 2021 |archive-url=https://web.archive.org/web/20210413225149/https://books.google.com/books?id=sygDAAAAMBAJ&pg=PA31 |url-status=live }}</ref>

Major technological advances in the 1950s and 1960s allowed the production of large tonnages at an affordable cost:
* AOD process ([[argon oxygen decarburization]]), for the removal of carbon and sulfur
