Product Details

SAF 2205 Duplex corrosion resistant Stainless Steel ( hereinafter  referred to as DSS), refers to the ferrite and austenite each account for about  50%, the content of general is a youthful appearance also need to achieve at  least 30% of the Stainless Steel.

In the case of  low C, Cr content was 18%~28% and Ni content was 3%~10%.Some steel also contain  Mo, Cu, Nb, Ti, N and other alloy elements. This kind of steel has the  characteristics of austenitic and ferritic stainless steel.

Compared with  ferrite, it has higher plasticity, higher toughness, no room temperature  brittleness, and the corrosion resistance and welding performance are  significantly improved.
