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.
