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. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, machining, joining, and surface treatment.
