For Q235 steel, Q represents the yield limit of this material, and the following 235 refers to the yield value of Q235 steel, which is about 235 MPa. The A573 Gr 70 plate, Q235 steel yield strength decreases with the increase of the thickness of the material.
The company has formed a production scale of steel plates, steel pipes, steel profiles, and other products, with a planned layout of science, advanced A573 Gr 70 plate technology and equipment, reasonable resource allocation, environmental protection, energy saving and high efficiency. BBN company has become a large-scale iron and steel enterprise integrating steel A573 Gr 70 plate production, mineral resource development, steel structure and engineering construction, real estate and modern logistics.

Phosphorus is a very harmful element in A573 Gr 70 plate steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of A573 Gr 70 plate steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.
