Q420B high strength steel plate

Q420B is a low alloy high strength structural steel. Q420B is not only a high strength steel, but also a low carbon steel. It's just that its tensile strength is a little higher. The yield strength of Q235 is 235N/mm^2 while the yield strength of Q420 is 420N/mm^2. Due to its low carbon content, it cannot be tempered and processed, and it is still impossible to process shafts, gears, etc. But it is very good to make steel plates, and its strength is much higher than Q235. Q420 has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance; good corrosion resistance and certain wear resistance.

Q390E High strength steel plate

Q390E steel plate is a high-strength steel plate, which is widely used in buildings, bridges, vehicles, ships, pressure vessels, etc. It has excellent mechanical properties and welding properties, and can meet the design and manufacturing requirements of various complex structures.

Q390D high strength steel plate

Q390D is a low alloy high strength structural steel. The Q390D steel plate is implemented in the following standards: GB/T1591-2018 standard, GB = national standard, 1591-2018 = steel plate standard production number Q390D is not only a high strength steel, but also a low carbon steel. Q390D has high yield strength, good fatigue resistance, high toughness and low brittle transition temperature, good cold forming performance and welding performance, good corrosion resistance and certain wear resistance.

Q390C high strength steel plate

Q390C high-strength structural steel plate, as the name implies, is mainly composed of iron and carbon elements. Through special smelting process and heat treatment technology, it has high tensile strength and yield strength. During the manufacturing process, this steel plate undergoes multiple rolling and annealing treatments, making its grains finer and the structure more uniform, thereby further improving its mechanical properties.

Q390B high strength steel plate

Q390B is a low alloy high strength steel plate, which is widely used in mechanical equipment, steel structure facilities, subway projects, bridge projects, and high-rise building structures. The "390" in its name means that the yield strength is greater than or equal to 390MPa, and "B" stands for room temperature.

S355J0W weathering steel plate

S355J0W is a weathering steel plate, which is an improved atmospheric corrosion resistant structural steel plate according to the EN 10025-5 standard. It is a low-alloy steel made by adding a certain amount of alloy elements to ordinary steel plates. It has good mechanical properties, welding properties, etc. The longer the time, the more obvious the corrosion resistance. The atmospheric corrosion resistance of weathering steel is 2-8 times that of ordinary carbon steel.

S355J2W weathering steel plate

S355J2W is an improved atmospheric corrosion resistant structural steel. It is a fine-grained steel that enhances the ability to resist atmospheric corrosion under ambient temperature. In order to achieve the corrosion resistance, certain specific alloy elements such as P, Cu, Cr, Ni, Mo, etc. are added to form a protective oxide layer on the metal surface under various climatic conditions. It is widely used in high-speed rail bogies, welding, bolting and riveting parts.

S235J0WP weathering steel plate

S235J0WP is a weathering steel plate, where "S" stands for structural steel, "235" represents a yield strength of 235MPa, "J0" represents the minimum impact energy at 0°C, "W" indicates that the steel is improved for atmospheric corrosion resistance, and "P" indicates that the steel is classified in a larger phosphorus content (only when the steel is S355).
