H13 Tool Steel

H13 tool steel is the most popular steel grade for various Industries. The main features of high alloyed Cr-Mo-V Hot Work tool steel is high wear resistance to thermal shock and to heat cracking, good mechanical characteristics & toughness in hot condition.H13 appears excellent machinability with constant hardness during production activities.

The equivalent steel grade H-13 / SKD61 / AISI H13 normally available in the annealed condition but in some specific applications, we provide Pre-Hard H13 with its standard hardness 460-500 BHN. Utilized for ejector pins, apparatus holders and shrink fit chucks.

H13 tool steel is a widely used hot work tool steel that belongs to the AISI (American Iron and Steel Institute) H-series steels. It is renowned for its exceptional combination of high hardness, toughness, and heat resistance, making it well-suited for a variety of applications in hot work tooling. H13 tool steel contains a composition of approximately 1.4% to 1.6% carbon, 4.75% to 5.5% chromium, 0.3% to 1% molybdenum, 1% vanadium, and smaller amounts of other alloying elements such as silicon and manganese. This specific composition contributes to its excellent properties, including high hardness, good abrasion resistance, high toughness, ductility, machinability , polishability, good high-temperature strength and resistance to thermal fatigue, very limited distortion during hardening.

Vanadium and molybdenum serve as strengthening elements in steel H13. Die steel H13's high chromium content helps it resist softening when utilized at high temperatures. H13 die steels have good red hardness and a great mix of stress and abrasion resistance. It can endure quick cooling and withstands early heat testing. It is frequently used in hot and cold work tooling applications due to its extraordinary combination of heat resistance, hardness, and toughness. This makes it a great choice for applications involving high-temperature settings and difficult mechanical conditions.
