2. Product description
Hot rolling is amill process which involves rolling the steel at a high temperature (typicallyat a temperature over 1700° F), which is above the steel’s recrystallizationtemperature. When steel is above the recrystallization temperature, it can beshaped and formed easily, and the steel can be made in much larger sizes. Hotrolled steel is typically cheaper than cold rolled steel due to the fact thatit is often manufactured without any delays in the process, and therefore thereheating of the steel is not required (as it is with cold rolled). When thesteel cools off it will shrink slightly thus giving less control on the size andshape of the finished product when compared to cold rolled.
Uses: Hot rolled products like hot rolledsteel bars are used in the welding and construction trades to makerailroad tracks and I-beams, for example. Hot rolled steel is used insituations where precise shapes and tolerances are not required.
