Difference Between Hot and Cold Rolled Steel Metal
Sep 11, 2014 · 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 steels 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.
Aug 19, 2020 · The cold-rolled formed steel allows local buckling of the section, which can make full use of the bearing capacity of the bar after buckling; while the hot-rolled steel does not allow local buckling of the section. 2. Hot-rolled steel and cold-rolled steel have different causes of residual stress, so the distribution on the section is also very
Hot Rolled Steel & Cold Rolled Steel - Difference & Hot rolled steel is a good choice when tight tolerances are not of utmost importance. There are many fields where that is the case. Its great advantage in price matters more than precision.
