Our H13 tool steel is a chromium molybdenum hot work steel. H13 tool steel is well known for its outstanding hot hardness and abrasion resistance. H13 tool steel is ideal material for a various hot work usages. Because of its general hardness and toughness, H13 steel can also be used in cold work applications.
H13 steel material can be available as bars, flats, billets and forgings. The typical thermal processing applications of our H13 steel include die casting dies, forging dies, extrusion dies, inserts, plungers, cores, ejector pins, sleeves, slides, dummy blocks, mandrels and hot shears. Other tooling and structural applications include beams, shafts, punches, torsion bars, shrouds and ratchets.
H13 tool steels have good red hardness and a great mix of stress and abrasion resistance. It can endure quick cooling and withstands early heat testing. It is frequently used in hot and cold work tooling applications due to its extraordinary combination of heat resistance, hardness, and toughness.

For hot work applications, H13 tool steel is used in the hardness range of HRC 38 to 48. The usual hardness range for die casting dies is HRC 44 to 48 requiring a temper at approximately 1100°F. For improved shock resistance, the steel is often tempered at temperatures approaching 1150°F, resulting in hardness of HRC 40 to 44.
H13 steel hardness range is 28-53 HRC varies with tempering temperature, all specimens are air-cooled from 1025 °C (1875 °F) and tempered at temperature for 2 hours.
