ASP 2030



Description


A Cobalt high-alloyed powder metallurgy high-speed steel corresponding to PM 30 + Co. The high-compressive strength and exceptional abrasive wear-resistance makes PM 30 high-speed steel suitable for demanding cold work applications and for cutting tools as an alternative to AISI M42 or other Co-alloyed high-speed steels. The PM process gives this steel excellent machinability, as well as a good dimension stability during heat treatment. We are also constantly impressed with PM 30’s temper-resistance and through-hardening properties

Heat Treatment

  • Soft annealing in a protective atmosphere at 850-900°C for 3 hours, followed by slow cooling at 10°C/h down to 700°C, then air cooling.
  • Stress-relieving at 600-700°C for approximately 2  hours, slow cooling down to 500°C.
  • Hardening in a protective atmosphere at a temperature suitable for chosen working hardness. Pre-heating in 2 or 3 steps depending on tool dimension- design and austenetising temperature, last step 50°C below chosen austenitising temperature. Cooling down to 40-50°C.
  • Tempering at 560°C three times for at least 1 hour each time. Cooling to room temperature (25°C) between temperings.
