Steel Standard and Grade AISI H13; ASSAB 8402; DIN 1.2344; JIS SKD61 H13 Hot Work Tool Steel is an air hardening tool steel which combines a ver y good red-hardness with toughness and covers a wide variety of applications. H13 hot work tool steel may be water cooled in service and gives high temperature strength and wear resistance. H13 Hot Work Tool Steel Features: Good high temperature strength toughness and anti high temperature fatigue properties, can withstand sudden changes in temperature, suitable for a long-term work at high temperatures, has good cutting and polishing performance. Supply Condition and Hardness: Annealing, the hardness ≤ 229 HBS Quenching and Tempering Specification: Quenching temperature 1025 ~ 1070° C, the first tempering temperature 560° C, the second time 580° C. H13 Hot Work Tool Steel of Application: 1) Manufacture aluminum die-casting mold 2) Manufacture bearing rings rough hot upsetting punch 3) The best materials to manufacture large and medium-sized aluminum die casting, hot die, extrusion die. 4) Apply to manufacture aluminum, zinc, copper alloy extrusion die, die casting, forging die and hot shear blades, etc. 5) An ideal material for manufacturing mandrel. 6) Apply to manufacturing long life plastic mold.
