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.Sandvik SANBAR 23 is an air-hardening, high chromium molybdenum alloy steel suitable for carburizing and with good response to surface induction hardening. It has high fatigue strength and wear resistance in the case hardened condition. The alloy is used for extension and shank rods.
