Is Cold-Rolled Steel Stronger? - Sparkous

Precise production of the cold-rolled sheet is higher than that of the hot-rolled sheet: width, length, angles. A hot-rolled sheet is cheaper than a cold-rolled sheet, but when cooling, the sheet is compressed, and it is impossible to predict the size and shape as with a cold-rolled sheet. Cold-rolled sheets do not crack when bent.

Difference Between Hot and Cold Rolled Steel | Metal ...

Hot Rolled Steel. Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel's recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes.
