The company is a leading company that sells Q310GNH weather resistant steel plate equivalent steel plate products in the Central Plains region and has a high reputation in the steel plate industry. Since its establishment, the company has always adhered to the business philosophy of "integrity cooperation and common development", and has sold Q310GNH weather resistant steel plate equivalent steel products with various materials. The products are widely used in petroleum, chemical, construction, boiler, decoration, offshore operations, electric heating, gravity machinery and other industries.

The yield strength of Q310GNH weather resistant steel plate equivalent A32, D32, E32, F32 is not less than 315N/mm^2, and the tensile strength is 440~570N/mm^2. The grades A, D, E and F indicate that they can be 0 and -20 respectively. The impact toughness can reach -40℃, -60℃.

Q310GNH weather resistant steel plate equivalent, Q345B low alloy steel has outstanding characteristics, such as:
First, Q345B low alloy steel has good toughness. It is easy to bend and stretch, not easy to break, and can be used for multiple processing. Second, Q310GNH weather resistant steel plate equivalent, Q345B low alloy steel is easy to weld and can be used for assembly. Third, Q345B low alloy steel has good strength, good compression resistance and long service life. Fourth, the weather resistance of Q345B low alloy steel is good, and the use is not affected whether it is winter or summer.

The basic phases of Q310GNH weather resistant steel plate equivalent, structural steel in the annealed state are ferrite and carbide. The alloy elements are dissolved in ferrite to form alloy ferrite, which depends on solid solution strengthening to increase strength and hardness, but at the same time reduce plasticity and toughness. The addition of alloying elements reduces the carbon content of the eutectoid point, which increases the proportion of pearlite in the structure and reduces the distance of the pearlite layer. This also increases the strength of the steel and reduces the plasticity.
