The yield strength of 2205 duplex stainless steel is twice that of austenitic stainless steel, which allows designers to reduce weight when designing products, giving this material a price advantage over 316 and 317L. 2205 has better resistance to stress corrosion cracking than 304 and 316L, and can also resist point corrosion and crevice corrosion caused by chlorides. This duplex stainless steel is particularly suitable for environments with chloride and hydrogen sulfide present, such as marine applications and oil and gas production.
