Features
High speed steel rolls has high hardness and wear resistance at high temperatures. It is pro-duced by centrifugal method,the core made of ductile iron. By composition and heat treatment process control, the working layer hardness up 80-85HSC, the martensitic matrix distribution of vanadium, tungsten, niobium molybdenum carbide composite to ensure the working layer hard-ness uniform, female wearuniform. Such rollers for the finishing stand, increase working time, improve the surface quality of rolled products.
