- What Are Cold Rolled finishes?StandardsPost Production Processing to Improve Corrosion ResistanceDifferences Between AlloysCold rolled finishes apply to flat products such as sheet or coil, with thickness less than about 5mm and usually less than 3mm. They are firstly hot rolled into a strip (or cast into a slab which is hot rolled into a strip) and then cold rolled. Cold rolling reduces the thickness by at least 50%. This smooths the surface, refines the grain structure and causes differences in the mechanical properties along and across the rolling direction. In the case of austenitic and duplex alloys, the process hardens and strengthens thMycron Steel Berhad A pioneer in Cold Rolled Coils (CRC 8 rows · With improved surface quality, higher grade material and competitive prices, Mycron Steel

Cold-rolled sheet steel is produced from hot-rolled sheet with additional processing steps such as pickling, cold reduction, annealing and temper rolling. Cold-rolled steel is a product that has been cold reduced, as opposed to hot-rolled, in order to impart specific mechanical properties, surface finish, gauge tolerance and strip shape. Difference Between Black Steel and Bright Drawn Steel Sep 29, 2014 · All cold products provide a superior surface finish, and are superior in tolerance, concentricity, and straightness when compared to black steel. Cold finished bars are typically harder to work with than black steel due to the increased carbon content. However, this cannot be said about bright drawn sheet and black steel sheet.
