Hot Rolled Steel Sheet and Plate Hot rolled steel sheet and plate provides a rougher surface than cold rolled steel and plate.When galvanized it is also regularly used in applications where corrosion resistance is a necessity.High strength and highly formable HRHot Rolled Steel/Pickled OiledHot rolled sheet steel is rolled in a continuous hot strip mill at temperatures starting at about 1280°C.The steel passes through roll stands that progressively reduce it to the ordered thickness.Since the temperature at which the steel is coiled is approximately 650°C the surface of the as rolled product has a thin layer of oxide (scale.)

Technique # 1.Hot Rolling The rolling of metals above the recrystallisation temperature is called hot rolling.The temperature at which new grains are formed in the metal is known as recrystallisation temperature.This temperature should not be too high; otherwise the metal will burn and become unsuitable for use.The process of hot rolling is shown in Fig.2.6.
