Austenitic stainless steel characterized by a combination of good hot-rolling and good cold-rolling properties, good strength and ductility, and good welding properties, with resistance to intergranular corrosion in the as-welded condition. The steel contains about 17.5 to 22.5 percent chromium, about 5 to 9.5 percent nickel, at least 2.5 percent but less than 7 percent manganese, with a nitrogen content of about 0.2 to 0.4 percent, carbon not exceeding 0.040 percent, and remainder substantially iron. Where desired, there may be employed columbium in amounts up to about 1 percent and/or molybdenum up to about 3 percent. The steel is made available in the form of hot and cold flat-rolled products, as well as wire. It is suited to a wide variety of applications in the arts.
