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.CRUSADER is a DESEGATIZED* high-speed tool steel. It has an outstanding balance of red hardness, edge toughness and wear resistance. Additional carbon and vanadium content provide superior abrasion resistance and maximum cutting qualities. CRUSADER is a desirable steel for machining operations which require a smooth workpiece finish as in form-tool cutting and roll turning.
