Duplex stainless steels have a microstructure of nearly equal portions of austenite and ferrite. This microstructure ensures that they are much more resistant to stress corrosion cracking (SCC) than conventional austenitic stainless steels.
2205 will be used in applications requiring better corrosion resistance, such as environments containing chlorides and polluted marine environments, desalination plants, etc.
The higher chromium, molybdenum and nitrogen contents give 2205 significantly improved pitting and crevice corrosion resistance in the presence of chlorides.
2205 also has better general corrosion resistance than the 316L types in most environments. 2205 is a highly suitable material for service in environments containing chlorides and hydrogen sulphide such as marine environments and the oil and gas extraction and processing industries.
