Hot Rolled Checkered Steel Plate

It consists of Q+ number + quality grade symbol + deoxidation method symbol. Its steel number is preceded by "Q", which represents the yield point of the steel, followed by a number indicating the yield point in MPa. For example, Q235 represents a carbon structural steel with yield point (σs) of 235 MPa. ② If necessary, the steel number can be marked after the quality grade and deoxidation method symbol. The quality grade symbols are A, B, C and D respectively. Symbol of deoxidation method :F stands for boiling steel; b stands for semi-killed steel; Z stands for dead steel; TZ stands for special sedative steel. Sedative steel may not be marked, that is, Z and TZ may not be marked. For example, Q235-AF indicates grade A boiling steel.

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 Mild Steel Sheet Metal is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes. Mild Steel Plate 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.
