Duplex stainless steels are called “duplex” because they have a two-phase micro-structure consisting of phases of ferritic and austenitic stainless steel. This structure provides a unique set of benefits.
Strength
Duplex stainless steels are about twice as strong as regular austenitic or ferritic stainless steel.
Corrosion Resistance
As with all stainless steels, corrosion resistance depends mostly on the composition of the stainless steel. The composition of this steel makes it better at resisting corrosion.
Toughness and Ductility
Duplex stainless steel have significantly better toughness and ductility than ferritic grades.
