| Summary | 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 properties can mean some compromise when compared with pure austenitic and pure ferritic grades. | ||||||||
