ASSAB PM 30 SUPERCLEAN
HIGH SPEED STEEL WITH EXCELLENT COMPRESSIVE STRENGTH
ASSAB PM 30 SUPERCLEAN is a cobolt alloyed powder metallurgy high speed steel with excellent compressive strength and good abrasive wear resistance. ASSAB PM 30 SUPERCLEAN is suitable for demanding cold work applications and for cutting tools as an alternative to AISI M42 or other co-alloyed HSS. The pm process gives a good machinability and grindability as well as a good dimension stability during heat treatment.
