What is "Cold Rolling" Stainless Steel and Other Metals?
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.
2021625 · Cold rolling is a round bar that is rolled into regular sections on a cold rolling mill to improve its strength and adhesion to concrete. When the steel bar is rolled in cold rolling, it deforms both lengthwise and crosswalk at the same time, so its plasticity and internal structure uniformity can be well maintained.
Hot Rolled vs Cold Rolled Steel: Overview and Differences
