High hardenability, excellent wear resistance and hot toughness. has good thermal shock resistance, (ESR) H13 has greater homogeneity and an exceptionally fine structure, resulting in improved machinability, polishability and high temperature tensile strength.

Pressure die casting tools, extrusion die, forging dies, hot shear blades, stamping dies, plastic molds, Hot work mandrels, ESR H13 is great for aluminium die-casting tools and plastic mold tools requiring a very high polish.
