M4 High Speed Steel
M4 High speed steel
M4 high-speed steel is a high-performance alloy tool steel widely used in the manufacture of cutting tools and molds. Its main characteristics are excellent wear resistance, hot hardness and oxidation resistance. The chemical composition of M4 steel includes a high content of molybdenum (Mo), which makes it extremely resistant to wear and high-temperature strength, and can maintain high hardness at high temperatures. It also contains a certain proportion of tungsten (W) and cobalt (Co), which further enhances its resistance to thermal fatigue and corrosion.
