SS2376 Duplex stainless steels have a two-phase microstructure of austenite and ferrite grains. The duplex structure gives this family of stainless steels a combination of attractive properties: 
Strength: Duplex stainless steels are about twice as strong as regular austenitic or ferritic stainless steels.
