ASSAB PM 23 SUPERCLEAN

SUPERIOR MACHINABILITY AND GRINDABILITY

ASSAB PM 23 SUPERCLEAN is a high alloyed powder metallurgical high speed steel with a good abrasive wear resistance in combination with a high compressive strength. It is suitable for demanding cold work applications like blanking of harder materials such as carbon steel or cold rolled strip steel and for cutting tools. The machinability and grind ability are superior to conventional high speed steel and so is the dimensional stability after heat treatment.
