Properties


PM23 is a kind of high cutting and cold ultra-pure powder metallurgical tool steel not containing cobalt, which integrated high toughness and wear resistance, so it has excellent grinding performance. It is very suitable for different types of PVD coating, the maximum of nitride layer thickness is controlled range from 2 to 15 m.
