High Wear-resistant 1.3343 / M2 / SKH51 High Speed Special Tool Steel Round Bar
Introduction:
M2 steel is a general purpose molybdenum high speed steel. M2 steel is characterized by balanced combination of abrasion resistance, toughness and good red hardness. Due to its comparatively low carbon content, M2 steel has an excellent combination of toughness properties and abrasion resistance when properly hardened and tempered. M2 steel is used in a wide used for all kinds of cutting tool, knife and punch and die applications.
