Research Status of Corrosion Behavior of 316LSS and 2205DSS

The chemical and electrochemical methods for studying 316L austenite stainless steel and 2205 duplex stainless steel are summarized and the corrosion sensibility are explored.The application,development and the corrosion problems during application and development of 316L and 2205 stainless steels are discussed.The corrosion resistance of 2205 duplex stainless steel is more excellent than 316L austenite stainless steel under the same conditions.Due to the eminent corrosion resistance of 2205 stainless steel,using 2205 stainless steel to replace single phrase 316L stainless steel at some low temperatures is possible.
