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.

Difference Between Hot Rolled Steel and Cold Rolled Steel

Cold rolled steel is essentially hot rolled steel that has had further processing. The steel is processed further in cold reduction mills, where the material is cooled (at room temperature) followed by annealing and/or tempers rolling. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes.

Steel mills produce cold-rolled coils within the 0.060" – 0.105" thickness range. Due to work hardening, one can produce cold-rolled coils of tighter dimensions without compromising their strength. Such metal is lightweight and durable. Thus, a cold-rolled steel sheet exhibits strength comparable to a 50% thicker hot-rolled one.

Typical products of cold rolling are sheet steels for automotive applications such as soft grades for deep drawing of car body panels or high-strength ...

Cold roll forming process description | voestalpine Pro

Coil feeder. Cold roll forming consists of gradually and continuously forming a steel profile. The method consists initially unrolling the strip of a steel coil, whose width corresponds to the developed of the finished profile. This band, also called strip, is then engaged flat in a succession of several rolls called rollers whose shapes and ...
