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.ESC VAGS is an alloy steel capable of being heat treated to produce wide range of tensile strengths combined with good ductility and resistance to shock. It is recommended for high strength machine parts, gears, shafts, bolts, connecting rods, etc.
