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.
Edward G. Budd
During the Great Depression in the 1930s, Budd pioneered the fabrication of stainless steel and helped create the "Pioneer Zephyr", a streamlined train for the Chicago, Burlington and Quincy Railroad. Budd stainless steel railway cars were very successful for many years. During World War II, Budd was also the original maker of the Bazooka projectile and the rifle grenade. He and his company were also instrumental in the development of the radial disk brake and the automatic wheel line.
