* Cold rolled steel is our most common and commonly used cold rolled products.Its brand can be generally divided into: ST12, ST13, ST14, ST15, ST16 and so on. * ST12 is German standard (DIN1623), It's ordinary cold rolled steel. In principle, ST12 can only be bent and formed, and no stamping is allowed. * Surface quality: FC, FB * ST12 Chemical Component * Chemical C Mn P S Al elements * Percentage 0.10 0.50 0.035 0.035 0.020 * ST12 Mechanical properties a MPa 280, MPa 270 410, L0=80mm b=20mm % 28

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 steelâ??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.
