Duplex SS are two-phase alloys containing equal proportion of ferritic and austenitic phases in their microstructure, providing a combination of the corrosion resistance of austenitic stainless steels with greater strength.
Duplex stainless steels get their name from their two-phase microstructure.
While exact ratios vary by grade, most duplex steels have a structure that is roughly 50-percent austenite and 50-percent ferrite.
