Steel Rolls

Forged Steel: Hardened forged steel rolls manufactured for the cold rolling of steel and non-ferrous metals are of high carbon CR-Steel. Additionally, as the case may be, other alloying elements are added to enhance a specific property for better roll performance. The most common alloying elements are Ni, Cr, Mo, and V. The selection of a roll material depends mainly on the properties demanded by the rolling process, such as the following: hardness, hardness penetration, structure, crack- resisting properties, roughness, wear resistance, etc.
