An austenitic stainless steel for sour gas service has been developed. The new steel has been shown to offer high strength, i.e., 0.2% PS exceeding 42kgf/mm/sup 2/ (414MPa) under solution-annealed conditions, along with excellent resistance to sulphide stress corrosion cracking, pitting corrosion, and crevice corrosion, in comparison with conventional martensitic stainless steel such as CA-6NM, duplex stainless steel such as ASTM A790 UNS S31803, and austenitic stainless steels such as Type 316. Its higher resistance to corrosion cracking, etc., then Type 316 was thought to be attributable to the higher contents of Cr, Mo, and N, which help to form more stable passive film in a shorter time.
