Cold rolling means that hot rolled steel coil is rolled below recrystallization temperature after pickling, and its finished product is full hard coil. After annealing process for full hard coil, the finished product is cold rolled production. The thin gauge cold rolled steel sheet and strip steel have advantages of low surface roughness, high dimension accuracy and good mechanical properties etc, and which have

Tinmill Products SteelTin Coated Sheet (TCS) is similar to ETP, except the thickness of the material is greater than 0.015. The substrate is Cold Rolled (CR) steel instead of Tinmill Blackplate (TMBP), so the product uses flat roll specification designations instead of tinplate designations.
In simple terms, cold rolling is the process of strengthening steel by changing its shape without using heat. Cold rolling, unlike hot rolling such as with hot rolled steel, can only occur when a metal is below its re-crystallization temperature. Where hot rolling is performed using high temperatures, cold rolling is performed at room temperature. cold rolled annealed steel strip, cold rolled annealed Jun 18, 2021 · cold rolled annealed steel strip, cold rolled annealed
