Product Description
General
ASP 30 is a high alloyed powder metallurgical (PM) high speed steel characterized by:
  • high wear resistance
  • high compressive strength at high hardness
  • good through-hardening properties
  • good toughness
  • good dimensional stability during heat treatment
  • good grindability and machinability
  • very good temper resistance

Applications
ASP 30 is a cobalt alloyed high performance PM high speed steel. The cobalt addition of approx. 8,5% has a positive influence on the hot strength/hot hardness, temper resistance and modulus of elasticity. The presence of cobalt has little influence on wear resistance. As cobalt does not form carbides, the wear resistance of ASP 30 is more or less the same as for steels with the same base analysis but without cobalt (e.g. ASP 23). On the other hand, its presence reduces the toughness and hardenability somewhat but increases compressive strength and high temperature properties.

Properties Profile For Cold Work Applications
  • The combination of high wear resistance and unusually good compressive strength can be put to use in tooling for heavy forming operations.
  • In some cold work operations, the active surface (e.g. cutting edge or forming surface) of a tool can reach temperatures in excess of 200°C (390°F). Such conditions can be found in tooling running on high speed presses. Also, development of high temperatures in the tooling can be expected in heavy forming operations.
