> It widely used in hot work and cold work tooling applications.
> It resists thermal fatigue cracking which occurs as a result of cyclic heating and cooling cycles in hot work tooling applications.
> Its excellent combination of high toughness and resistance to thermal fatigue cracking (also known as heat checking) H13 is used for more hot work tooling applications than any other tool steel.
> With good stability in heat treatment, H13 is also used in a variety of cold work tooling applications. In these applications, H13 provides better hardenability (through hardening in large section thicknesses) and better wear resistance than common alloy steels.
> Also available as Electro-Slag-Remelted (ESR) products as well. The remelting processes provide improved chemical homogeneity, refinement of carbide size.

Heat Treatment:
Forge: At 1050° C-1095° C Cool slowly and anneal then.
Annealing: At 843° C-898° C; Cool slowly in furnace
Stress Relieving: Heat slowly to 566° C-676° C, and then cool in still air.
Hardening: Preheat to 815° C and then heat to 1010° C and hold for 15 to 40 minutes. Air cool (air quench)

APPLICATIONS: Inserts, cores, and cavities for die casting dies, die casting shot sleeves, hot forging dies, extrusion dies, and plastic mold cavities and components that require high toughness and excellent polishability.
