product presentation
High Speed steel(HSS)roll has high hardness and abeasive resisance under high temperature.It is made by centrifuge method;the core part is made of nodular cast iron.Through component and heat treatment technique,the hardness in working layer is able to reach 80-85HSC;matrix in martendite contains V,W,Mo compound carbide so as to assure the even hardness and aperture abrasion in working layer.This kind of roller is applicable to finishing rack to expand working period and improve surface quality of rolling materials.
