Duplex-SuperDuplex Stainless Steel

Duplex stainless steels are microstructurally constituted by two phases: ferrite and austenite. As alloying elements, they contain iron, chromium, carbon and nickel, the latter element to lower content than in austenitic stainless steels.

In general, they have higher mechanical properties and corrosion resistance than ferritic and austenitic stainless steel.
