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.ALZ 301 is an austenitic stainless steel with good cold formability, toughness and high mechanical properties. Its corrosion resistance is similar to that of ALZ 304. Because of its higher carbon content, the risk for sensitization during welding is higher. Therefore, its use is limited when substantial welding is necessary.
