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.

A catalyst for sustainable operations
Nickel-containing catalysts are widely used in the refining and petrochemical industries worldwide. At end-of-life, catalysts are either sent to landfill or sent for recycling to recover the valuable metals they contain. Refineries in Kuwait are changing the way they handle spent catalysts.
