  • Product Detail

Q235GHN steel plate commonly used in several sizes?
The commonly used sizes of Q235GHN steel plates are grades A, B, C and D (GB/T 700-2006).
Q represents the yield limit of this material, and the latter 235 refers to the yield value of this material, which is around 235MPa. And the yield value decreases as the material thickness increases. Due to the moderate carbon content, good comprehensive performance, and matching strength, plasticity and welding performance, it is the most widely used.
The complete representation method is: Q235--Quality grade symbol · Deoxidation method symbol The quality grade is divided into A, B, C, D, E, followed by A grade with poor quality, and D grade with the highest quality. The symbols of deoxidation methods are F, b, Z, TZ, which represent boiling steel, semi-killed steel, killed steel and extra-killed steel respectively, but in the naming method, the symbols of Z and TZ can be omitted.
Application of Q235GHN steel plate:
1. Widely used in construction and engineering structures. It is used to manufacture steel bars or build workshops, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc. It is also widely used as mechanical parts with low performance requirements. C, D grade steel can also be used as some professional steel.
2. It can be used for various mold handles and other unimportant mold parts.
3. The stamping material adopts Q235GHN steel plate. It can be used directly without tempering after quenching. The hardness is 36~40HRC, which solves the phenomenon that the punch is broken during use.
