- 2205 Stainless Steel
2205 is a duplex stainless steel with nearly equal proportions of austenite and ferrite when properly heat treated. This microstructure results in greater resistance to stress corrosion cracking than stainless steel 304 and 316L. 2205’s higher levels of chromium, molybdenum, and nitrogen, give it enhanced protection against pitting and crevice corrosion in the presence of chlorides.
Its yield strength is about twice that of austenitic stainless steels. 2205 steel is especially suitable
for applications in environments containing chlorides and hydrogen sulfide such as marine applications and oil and gas production.
Oil and gas industry piping, tubing and heat exchangers; pulp and paper industry bleaching equipment, liquor tanks and digesters; cargo tanks for ships and trucks; chemical processing industry pressure vessels, tanks, piping and heat exchangers; and food processing equipment.
