Who developed stainless steel?
Stainless steel
In 1912, Harry Brearley of the Brown-Firth research laboratory in Sheffield, England, while seeking a corrosion-resistant alloy for gun barrels, discovered and subsequently industrialized a martensitic stainless steel alloy. The discovery was announced two years later in a January 1915 newspaper article in The New York Times.[27] The metal was later marketed under the "Staybrite" brand by Firth Vickers in England and was used for the new entrance canopy for the Savoy Hotel in London in 1929.[35] Brearley applied for a US patent during 1915 only to find that Haynes had already registered a patent. Brearley and Haynes pooled their funding and with a group of investors formed the American Stainless Steel Corporation, with headquarters in Pittsburgh, Pennsylvania.[36]
Washington Steel Corporation
Washington Steel was founded in 1945
by T. S. Fitch who was a member of the U.S. War Production Board from 1942 to 1944. As a member of the Board's Steel Division, he saw a Sendzimir Cold Rolling Mill in operation and began to appreciate its potential value for rolling stainless steel into thin, high-accuracy sheets.
