Elwood Haynes was an American inventor, metallurgist, automotive pioneer, entrepreneur and industrialist. He invented the metal alloy stellite and independently co-discovered martensitic stainless steel along with Englishman Harry Brearley in 1912 and designed one of the earliest automobiles made in the United States. He is recognized for having created the earliest American design that was feasible for mass production and, with the Apperson brothers, he formed the first company in the United States to produce automobiles profitably. He made many advances in the automotive industry.

Stainless steel, also known as inox, corrosion-resistant steel (CRES) and rustless steel, is an alloy of iron that is resistant to rusting and corrosion. It contains iron with chromium and other elements such as molybdenum, carbon, nickel and nitrogen depending on its specific use and cost. Stainless steel's resistance to corrosion results from the 10.5%, or more, chromium content which forms a passive film that can protect the material and self-heal in the presence of oxygen.

Stainless steel is used for industrial equipment when it is important that the equipment be durable and easy to clean.
