ABSTRACT:
A stress corrosion resistant austenitic stainless steel essentially consisting of from 15.5% to 20% chromium, from 11% to 14% manganese, from 1.1% to 3.75% nickel, from 0.01% to 0.12% carbon, from 0.20% to 0.38% nitrogen, and balance substantially iron. Phosphorous may be present up to 0.06% maximum, sulfur up to 0.04% maximum, and silicon up to 1% maximum. The steel has high strength at room temperature, good stability when severely cold worked, good cryogenic strength and toughness, wear resistance and excellent fusion welding characteristics, making it useful for a multiplicity of cryogenic applications, fabrication of welded articles, and cold-drawn wire.
