Hot Rolled High Speed Tool Steel M2 / 1.3343 / SKH51 Round Bar
M2 mold steel is molybdenum mold steel, commonly known as wind steel, high speed steel, 6542, with carbide non-uniformity and high toughness advantages.
Easy to overheat, it should be strictly controlled quenching temperature, heat treatment protection requirements more stringent.
Because of its hardness and wear resistance, and more for the manufacture of cutting difficult cutting tools.
M2 high speed tool steel with carbide tendency, therefore, the more stringent requirements of heat treatment protection, suitable for shock and shock load to withstand the mold.
