Comparision of Stress Corrosion Resistance of 22Cr Duplex Stainless Steel, 304L and 316L Common Austenitic Stainless Steels in Chloride Solutions

The stress corrosion resistance of 22Cr duplex stainless steel in chloride solutions with different Cl- concentrations at various temperatures were analyzed by constant load method and constant strain method,and compared with that of 316L and 304L common austenitic stainless steels.The results showed that 22Cr duplex stainless steel had better SCC resistance in chloride solutions.
