♦ Introduction:
Grade M2 / 1.3343 steel is a general purpose molybdenum high speed steel.
Grade M2 / 1.3343 steel is characterized by balanced combination of abrasion resistance, toughness and good red hardness.
Due to its comparatively low carbon content, grade M2 / 1.3343 steel has an excellent combination of toughness properties and abrasion resistance when properly hardened and tempered.
Grade M2 / 1.3343 steel is used in a wide used for all kinds of cutting tool, knife and punch and die applications.
