HIGH SPEED STEEL T 1
M42 is a profoundly cobalt alloyed high speed steel to be utilized when the interest for hot hardness is of great significance. M42 has a decent machinability and a decent wear resistance. Great cutting performance can be accomplished from tools made in M42 high speed steel. With the high heat treated hardness of up to 70 Rockwell M42 high speed steel also offers excellent wear resistance.
