Stainless steel was invented in 1913 by Harry Brearley of Sheffield, working for Firth Brown Steels (now called Sheffield Forgemasters). SAE 304 stainless steel is the most common stainless steel today, invented by Dr William Herbert Hatfield FRS in 1924 at Firth-Vickers known as Staybrite 18/8, a chromium-nickel steel. Many Swiss watches were mostly made out of Staybrite.

There are varying tales as to the inspiration for Deere to create the invention he is famed for, the steel plow. In one version he recalled the way the polished steel pitchfork tines moved through hay and soil and thought that the same effect could be obtained for a plow. By early 1838, Deere completed his first steel plow and sold it to a local farmer, Lewis Crandall. Crandall spread word of his success with Deere's plow quickly, and two neighbors soon placed orders with Deere. By 1841 he was manufacturing 75 plows per year, and 100 plows per year in 1876.
