Duplex stainless steel S31803 is a ferritic-austenitic stainless steel, belonging to the second generation of medium alloy duplex stainless steel.It combines the most beneficial properties of ferrite and austenite.S31803 double-phase stainless steel is a kind of steel with good corrosion resistance and high strength. The content of chromium and molybdenum is very high, so it has excellent ability to resist pitting and uniform corrosion.Dual-phase microstructure ensures that the steel has high stress corrosion cracking resistance and high mechanical strength.
