H13 Steel

H13 Tool Steel is chromium hot work tool steels which are widely used in hot and cold work tooling applications. H13 tool Steel is classified as group H steels by the AISI classification system. This series of steels start from H1 to H19.

In steel H13, the molybdenum and vanadium act as strengthening agents. The chromium content assists die steel H-13 to resist softening when used at high temperatures. H-13 die steels offers an excellent combination of shock and abrasion resistance, and possesses good red hardness. It is capable of withstanding rapid cooling and resists premature heat checking. Tool Steel H13 has good machinability, good weldability, good ductility, and can be formed by conventional means.

Due to H13 tool steel excellent combination of high toughness and fatigue resistance, AISI H13 hot work tool steel is used more than any other tool steel in tooling applications

AISI H-13 tool steel is characterized by:

  • Good resistance to abrasion at both low and high temperatures
  • High level of toughness and ductility
  • Uniform and high level of machinability and polish ability
  • Good high-temperature strength and resistance to thermal fatigue
  • Excellent through-hardening properties
  • Very limited distortion during hardening

    • Applications of AISI H13 Tool steel

  • Dies
  • Die-holders
  • Liners
  • Dummy compression/transfer molds
  • Hot Sheaing
  • Injection molds
  • Shrink Rigs(e.g for cemented carbide dies)
  • Wear-resisting parts
