High chromium steel roll is produced by special casting technology of triple centrifugal casting and double composite technology. High chromium cast steel roll have good bite ability, high thermal resistance and high wear resistance. The Barrel hardness is between 70-85 SHD, It is widely used on roughing stand of hot strip and plate rolling mills which highly increase the mill rolls work life. Chemical component: Neck Hardness: 32-45 Tensile Strength: 350N/mm2 min
