摘要： An austenitic stainless steel which in wrought or cast, and annealed, condition exhibits excellent galling resistance, excellent stress corrosion resistance in chloride-containing environments, good resistance against intergranular corrosion, good high temperature oxidation resistance, and a high work hardening rate. The broad composition range is, in weight percent, about 13% to about 19% chromium, about 13% to about 19% nickel, 0.5% to about 4% manganese, 3.5% to about 7% silicon, up to about 0.15% carbon, less than 0.04% nitrogen, about 0.05% maximum phosphorus, about 0.05% maximum sulfur, and balance essentially iron except for incidental impurities. The steel can be readily worked with conventional equipment and has particular utility for applications in which moving metal-to-metal contact, corrosive attack and/or elevated temperature are encountered in combination. The steel can also be cast into articles of ultimate use, or utilized in power metallurgy techniques.

摘要： A method of cold-working and stress-relieving iron-chromium ferritic stainless steels of non-heat hardenable type in the AISI 400 series, thereby increasing the ultimate tensile strength while maintaining good tensile ductility. Cold-working is effected by peripherally contacting the steel, i.e., extruding and/or die drawing, to produce a "cellular structure" not attainable in cold rolling. Repetitive cold-working and stress-relief anneals between about 750.degree. and 1200.degree. F increase the ultimate tensile strength in increments and restore the tensile ductility substantially to that of the hot rolled and annealed material, while maintaining the tensile to yield ratio substantially constant. Ultimate tensile strength up to about 400 ksi in small diameter wire is attainable.
