product presentation
High speed steel roller maintain high hardness and wear resistance at high temperatures. Produced by centrifugal casting, the core is made of ductile iron, and the working layer hardness reaches 80–85 HSC. The martensitic matrix is distributed with vanadium, tungsten, niobium, and molybdenum composite carbides, ensuring uniform hardness in the working layer and even hole pattern wear. Mainly used in finishing mill stands, they can extend operation time and improve the surface quality of rolled products.
