Because of its high toughness and very 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 such as 4140.
Also available as Electro-Slag-Remelted (ESR) and Vacuum-Arc-Remelted (VAR) products as well. The remelting processes provide improved chemical homogeneity, refinement of carbide size, and the associated improvements in mechanical properties and fatigue properties.
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.
