H13 Tool Steel is a versatile chromium-molybdenum hot work steel has good thermal shock resistance and thermal fatigue cracking. H14 is able to handle some water cooling while in service. H13 ESR (electroslag remelting) has greater homogeneity and superior fine structure, which leads to improved machinability, polishability and high temperature tensile strength.  Alloy H13 has high hardenability, excellent wear resistance and hot toughness.

H13 has good toughness and good stability in heat treatment. This is available as ESR and in VAR (vacuum-arc-remelted) also.
