Powder metallurgical steels are HIP (hot isostatic pressed) consolidated from very small powder particles. With such technology, gas atomisation method has made it possible to produce spherical powder with high filling density and less oxygen content, therefore the properties and structures of the steel are much refined over conventionally produced steels.

Conventional

HIP and hot-formed high speed steel

There is no negative effect on the structure or carbide dispersion in powdered high speed steel

Characteristics of powder metallurgical steel:

  • Optimum hardness
  • Greatest durability
  • Improved wear resistance
  • Improved toughness (less chipping)
  • Excellent grindability (on resharpening)
  • Optimum homogeneity
  • Outstanding dimensional stability
  • High pressure loading capacity
