Hot Rolled Steel vs. Cold Rolled Steel | Swanton Welding

Steel's recrystallization temperature stands at 1700 degrees Fahrenheit. As such, during the hot rolling process the temperature must exceed that level. It's 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.
