High-speed steel is the alloy family that lets a cutting edge stay hard at the temperatures generated by high-speed machining — hardness that ordinary carbon tool steel loses within seconds. Alloyed with tungsten, molybdenum, vanadium and cobalt, HSS holds its edge to around 600 °C.
Range
- M-series molybdenum grades (M2, M35 and similar) — the general-purpose workhorses
- T-series tungsten grades for traditional tooling applications
- Cobalt-bearing variants for higher red-hardness in demanding cuts
- Supplied as round bar, flats and sheets in the annealed condition, ready for machining and heat treatment
Applications
Twist drills, taps and dies, milling cutters, broaches, saw blades and machine knives, punches, and wear parts where hardened carbon steel is not enough but carbide is unjustified.
How CSACI supplies HSS
Material ships annealed with certificates of conformity and origin plus SGS third-party inspection stating chemistry and annealed hardness. We quote by grade, section and quantity, and can consolidate tool steel with your broader steel program.
