Austenitic Manganese Steels

Austenitic Manganese Steels

The original austenitic manganese steel, having about 1.2 C and 12 Mn, was developed by Sir Robert Hadfield in 1882. Hadfields steel was unique because it integrated high sturdiness and ductility with high work-hardening capacity and also, typically, good resistance to wear.Many variants of the original austenitic manganese steel have been proposed, typically in unexploited patents, but ...
