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.AISI 5147 is a low-chromium (nominally 1% chromium), intermediate-hardenability alloy steel for medium-duty applications. It is normally hardened by quenching in oil. It has a wide range of applications for transportation equipment, farm implements, tools and industrial machinery.
