Technical properties:

AISI/SAE M4: High speed steel based on powder metallurgy with better wear and pressure resistance than AISI/SAE M3 and AISI/SAE M2, due to a very clean and homogeneous microstructure with evenly spread carbides optimising wear resistance. Working hardness: 62-65 HRC.


AISI/SAE M4: Stamping tools, precision cutting tools, machining tools, broaching tools, rotary knives, woodworking tools, gear shaper cutters, circular saw segments, metal saws, screw dies, countersinks, chasers, cold extrusion punches, deep drawing dies, plastic moulds with high wear resistance.
