Duplex stainless steel

Duplex stainless steel is a high-strength steel that has a ferritic–martensitic microstructure. It is a low-to-medium carbon material with between 5-50% volume fractional martensite islands that are dispersed in a soft ferrite matrix. In addition to martensite, bainite and retained austenite components can also exist.
