Low-carbon, iron-chromium-nickel stainless alloys containing more than 16 percent chromium, with sufficient nickel to provide an austenitic structure at normal temperatures. These alloys cannot be hardened by heat treatment, but can be hardened by cold working. They are normally nonmagnetic, but can be slightly magnetic depending on composition and amount of cold working.
