The History of Stainless Steel—Part 4

America Enters the Picture

G.E. Coates - June 01, 2013

Elwood Haynes

In the previous issue (Vol. 28, No. 1), we looked at the early development of stainless steels in Europe, but metallurgists in the United States were also working on experimental chromium-alloyed steels. Among them was Elwood Haynes, whose main interest was to improve his automobiles. An accomplished inventor, Haynes focused on hard, wear-resistant alloys and alloys suitable for spark plug applications. He succeeded notably in developing the Stellite® family of alloys, the early versions of which contained cobalt, chromium, carbon, molybdenum, tungsten, and nickel.
