1. For steel rolls, type of Aluminium Oxide can be varied to suit material hardness. 2. For CI & non ferrous rolls, Silicon Carbide is used and gives cosmetic effects on rolls. 3. For high alloy steel rolls like HcHcr, having low machinability and high hardness, combination of SG and 39C should be used.
