High speed steel, i.e. w 18 CR 4 V (W18Cr4V)
Hardness: HRC heat treatment: 63 ° - 65 °
High speed steel also known as tungsten steel
Carbon content is 0.7-0.8%, tungsten content is 17.5-19%, chromium content is 3.80-4.4%, vanadium content is 1.0-1.4%, silicon content is less than 0.4%, manganese content is less than 0.4%, molybdenum content is less than 0.3%.
the hardness is not much different from that of Tungsten Carbide rolers, but it is more suitable for the larger pipe diameter. The price is also slightly lower than that of Tungsten Carbide rolers. The wear resistance of high-speed steel is not as good as that of cemented carbide, but it is a better choice for customers whose pipe diameter is larger than Φ 18mm.
