High speed steel rolls
High speed steel centrifugal composition roll is high-carbon alloy steel in which outer layer containers Cr Mo W V Ni and Nb,and the complicated carbide structure are embedded in tempered martensite structures for controlling carbon content and comprehensive heat treatment,optimizing wear resistance and heat fatigue resistance.The surface structure with thin thickness oxide keeps the lower balance stress.
