Description:
S32205 is with 22% Cr and 3% Mo additions, which is 1% Cr and 0.5% Mo more than S31803, it performs much better than 316L grade in almost all corrosive media. The yield strength is about twice that of austenitic stainless steels. This allows the designer to save weight and makes the alloy more cost competitive when compared to 316L grade.
S32205 is with advantages as good weldability and workability, high resistance to corrosion fatigue, stress corrosion cracking (especially chloride stress corrosion cracking), erosion, and high energy absorption. Other advantages of Duplex are higher heat conductivity and low thermal expansion compared to austenitic stainless steels, high strength, good resistance to sulfide stress corrosion, and high resistance to pitting and crevice to corrosion
