Precipitation hardening stainless steel is a kind of stainless ones with high strength, toughness, as well as corrosion resistance and gain structural materials after hardening treatment. By adding different types & quantities of elements on the basis of different types and quantities of chemical composition of stainless steel, different types and quantities of carbides, nitrides, carbo-nitrides as well as intermetallic compounds can appear via hardening process, which enhance the strength and sufficient toughness of austenitic stainless steel.
