High Speed Steel

High Speed Steels (HSS)

High-speed steels (HSS) are a special class of tool steels primarily valued for their ability to machine and cut materials efficiently at high speeds. They are commonly used in power-saw blades, drills, and precision cutting tools. HSS alloys are composed of carbon, chromium, vanadium, molybdenum, or tungsten in various combinations, which enhance their hardness, durability, and cutting performance.
