The rolling deformation of metal below the recrystallization temperature is called cold rolling.
Cold rolled steel strip generally refers to the strip steel being rolled directly at room temperature without heating. Although, due to the distortion of the metal during cold rolling, a large amount of deformation heat is generated. Therefore, the strip steel may be hot after rolling, but it is still called cold rolling.
Hot rolling is hot processing, which allows the steel to recrystallize internally and make its material properties better.
The mechanical properties of hot rolling are better than cold rolling.
