High-speed Tool Steel

High-speed Tool Steel is a type of high-alloy tool steel containing relatively high proportions of alloying elements such as tungsten, molybdenum, vanadium, and chromium. It possesses extremely high hardness, wear resistance, and red hardness (the ability to maintain hardness at high temperatures). It can retain a sharp cutting edge even under conditions of high cutting speeds and intense frictional heat, thus being widely used in the manufacture of high-speed cutting tools, drills, milling cutters, taps, punches, and the like. High-speed tool steels are divided into two main categories: tungsten-based and molybdenum-based. Common grades include M2, M42, T1, etc., making them indispensable materials in modern metal cutting processing.
