This paper reports the development of an austenitic stainless steel for sour-gas service. The new steel has been shown to offer high strength, i.e., 0.2% PS exceeding 42 kgf/mm{sup 2} (414 MPa) under solution-annealed conditions, along with excellent resistance to sulfide stress corrosion cracking, pitting corrosion, and crevice corrosion, in comparison with conventional martensitic stainless steels such as CA-6NM, duplex stainless steels such as ASTM A790 (UNS S31803), and austenitic stainless steels such as type 316 (UNS S31600). Its higher resistance to corrosion cracking, etc., than 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.
