Product Details
High – speed steel roll material is high in vanadium, chromium, tungsten, molybdenum and other alloy elements. The type of carbide in roll is mainly MC or M2C. Has good thermal stability, high hardness. good wear resistance and harden ability, from internal to the work roll surface layer hardness almost no change, so as to ensure the roll from out side to inside are equally good abrasion resistance
