Hot rolled coil

Is hot rolled steel after high temperature heating of rolling steel, its strength is not high, but enough to meet our use, its plasticity, good weldability so we compare commonly used; Hot rolling is needed before or in the process of rolling of steel rolling heating material. General steel to be heated to above the recrystallization temperature of rolling.  Such as: over 1000 degrees, hot rolling is processed at high temperatures. Make internal steel recrystallization.

 Make it the material better. But hot rolling will not change the metal structure performance.
