Cold Rolled Products

Cold Rolled (CR) Sheet ï General Specification 1. Definition Cold Rolled Sheets (CR Sheets) are steel sheets processed in cold reduction mills, where the material is rolled at room temperature below its recrystallization temperature. This gives the sheet a smooth surface, tighter thickness tolerances, and improved mechanical properties. 2. Standards Common standards used for CR Sheets: IS 513 (India): Cold Rolled Low Carbon Steel Sheets and Strips JIS G3141 (Japan): Cold-Reduced Carbon Steel Sheets and Strip ASTM A1008 / A366M (USA): Cold-Rolled Carbon Steel Sheet EN 10130 (Europe): Cold Rolled Low Carbon Steel Flat Products
