Difference Between Hot and Cold Rolled Steel Metal hot rolled or welded structural steel

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.

Hot Rolled Steel vs. Cold Rolled Steel Swanton Welding

Steels recrystallization temperature stands at 1700 degrees Fahrenheit. As such, during the hot rolling process the temperature must exceed that level. Its much easier to shape and form steel at such temperatures, hence most complex and bulky designs form better under high temperatures. Hot rolling steel has its advantages and disadvantages.

Hot rolled VS cold rolled steel - American Welding Society

May 21, 2003 · for mild, low alloy steel, cold or hot rolled, stick welding it w/ 7018 is usually a good choice. the only difference you might notice when working w/ hot or cold rolled steel is hot rolled steel is easier to bend. prettier is all in the hands of the craftsman. i mean, w/ the right tools you can polish anything so it looks like you didn't even weld it.
