What are duplex stainless steels?
The term"duplex"describes the microstructure that is characteristic of this family of stainless steels which is typically equal parts austenite and ferrite. Duplex stainless steels characterized by high strength levels and provide a range of corrosion resistance levels. They are used in applications ranging form moderately corrosive architectural applications to corrosive industrial and seawaer environments. They have very good resistance the chloride stress corrosion cracking and provide better chloride crevice corrosion resistance than austenitic stainless steels with comparable pitting corrosion resistance.
