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.GUTERL H-13 is an air-hardening chromium-molybdenum-vanadium tool steel that finds wide use as dies in the forging, extrusions and die-casting industries. It has good hot hardness and wear resistance, extreme toughness and high resistance to heat checking and erosive action. Also, it has excellent machinability in the annealed condition and relatively good freedom from distortion and scaling during heat treatment. Among its many uses are dies to cast aluminum-base and zinc-base alloys, forging-die inserts, hot gripper and header dies, and aluminum and magnesium extrusion dies, inserts and support tubing.
