View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.Type 301 (UNS S30100) is an austenitic chromium-nickel stainless steel capable of attaining high tensile strength and ductility by cold working. It is not hardenable by heat treatment. Type 301 is essentially nonmagnetic in the annealed condition and becomes magnetic with cold deformation.
