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.SAE 1064 is a carbon steel with carbon at a high level (nominally 0.64% carbon). It has low hardenability and on austenitizing and liquid quenching it develops a hard surface with a soft, ductile core. It is used for a variety of railway equipment, heavy machinery parts, springs, shafts and a wide range of hand and machine tools that require strength and wear resistance with a ductile core.
