Cold rolling, however, cannot reduce thickness of workpiece as much as hot rolling in a single pass. The choice of the best steel for the forming tools must; not only take the process into consideration, but also the type of metal being formed and the number of parts to be produced. In this case, cold rolling is a method used for forming metal ...
Nov 13, 2019· Cold rolling is the most common method of work hardening. This involves the metal being passed through pairs of rollers to reduce its thickness or to make the thickness uniform. As it moves through the rollers and is compressed, the metal grains are deformed. Examples of cold-rolled products include steel sheets, strips, bars, and rods.

Cold-Formed Steel vs. Hot-Rolled Steel The differences between cold-formed and hot-rolled steel are not just in the thickness and the shapes. Since cold-formed steel members are formed at room temperature, the material becomes harder and stronger. Its lightweight makes it easier and more economical to mass-produce, transport and install.
