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 1050 is a water- and oil-hardening grade of carbon steel recommended for applications where a shallow-hardening steel of moderate strength and toughness suffices. It is commonly used for parts where induction hardening is employed and may be used in the austempered condition.
