Metal Rolling thelibraryofmanufacturing

Roll materials vary dependent upon the specific metal rolling process. Common roll materials are cast iron, cast steel, and forged steel. Forged rolls are stronger and more rigid than cast rolls but are more difficult to manufacture. In industrial metal manufacturing processes, rolls are commonly made from nickel steel or molybdenum steel alloys.
