Specifications
H13 Hot WorkTool Steel is a versatile chromium-molybdenum hot work steel.
n it widely used in hot work and cold work tooling applications.
n It resists thermal fatigue cracking which occurs as a result of cyclic heating and cooling
cycles in hot work tooling applications.
n 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.
n 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.
n Also available as Electro-Slag-Remelted (ESR) products as well. The remelting
processes provide improved chemical homogeneity, refinement of carbide size.
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.
Forge: at 900℃-1100℃ Cool slowly and anneal immediatedly
Annealing: at 850℃-870℃ Cool slowly in furnace
Stress Relieving: at to 600℃-650℃ Cool in still air
Hardening: Preheat at 650℃-850℃ raise to 1020℃-1050℃ Cool in air, iol or into salt bath held at 500℃-550℃ and then air cool
