Feature
High speed steel rolls exhibit high hardness and wear resistance at elevated temperatures. Produced by centrifugal casting with ductile iron cores,the working layer achieves 80-85 HSC hardness through controlled composition and heat treatment. Complex carbides of vanadium, tungsten, niobium, and molybdenum distributed in the martensitic matrix ensure uniform working layer hardness and consistent roll pass wear. These rolls are used in finishing stands to extend operation time and improve rolled product surface quality.
