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. Hot rolled steel is typically cheaper than cold rolled steel due to the fact that it is often manufactured without any delays in the process, and therefore the reheating of the steel is not required (as it is with cold rolled). When the steel cools off it will shrink slightly thus giving less control on the size and shape of the finished product when compared to cold rolled.
Because of the high strength, good toughness, easy processing and good weldability and other excellent properties of hot-rolled steel products, they are widely used in the manufacture of ships, automobiles, roads and bridges, construction, machinery, pressure vessels, home appliances, hardware, furniture, etc. industry.
