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 5046 is an alloy steel of fairly low hardenability. It is used in a number of machinery and engineering applications where its relatively low hardenability and moderate strength are satisfactory.
