The company sells special wide and thick steel plates of various specifications and materials such as Wuhan Iron and Steel, Anshan Iron and Steel, Chongqing Iron and Steel, Baosteel and other materials all year round. Available specifications for high strength P235GH steel: thickness 8-650mm, width 1.5-4.02m, length 3-27m, unit weight 35 tons. Our company can set rolling futures according to user requirements, and stock a large number of stocks of various materials (including plates and short-foot plates) for many years, and can also cut and draw materials and deliver special-shaped finished or semi-finished products according to user requirements.

What is the difference between Q345B steel and Q345A steel? high strength p235gh steel, Q345B steel and Q345A steel have slight difference in chemical composition: Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15; Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15. The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.

The wear-resistant plate high strength p235gh steel shows good wear resistance: the chemical composition of the alloy layer contains 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%, the macro hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Because of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and high strength p235gh steel hardness is more than twice as that of the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 1.5-2.5:1.
