High Speed Steel 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.
