Abstract

Duplex stainless steels are extremely corrosion resistant, work hardenable alloys. Their microstructures consist of a mixture of austenite and ferrite phases. As a result, duplex stainless steels display properties characteristic of both austenitic and ferritic stainless steels. This combination of propertiescan mean some compromise when compared with pureaustenitic and pure ferritic grades.Duplex stainless steels are in most cases, tougher thanferritic stainless steels. Strengths of duplex stainlesssteels can in some cases be double that for austenitic stainless steels.
