Q460C high strength steel plate

Q460C steel plate is a high-strength steel plate, which is widely used in bridges, buildings, ships, vehicles and large steel structures. Its strength level is 460MPa, with high yield strength and tensile strength, good low-temperature toughness and processing performance. The manufacturing process includes smelting, continuous casting, rolling and heat treatment. Q460C steel plate has excellent welding performance and can be connected by various welding methods. Appropriate process measures should be taken to ensure its quality and performance.

Q420E high strength steel plate

The grade of Q420E steel plate consists of four parts, among which "Q" represents yield strength, "420" means that the yield strength of the steel plate is 420MPa, and "E" means that the steel plate has good welding performance. Q420E steel plate has high yield strength and tensile strength, usually above 420MPa, and has good elongation and impact toughness. This enables Q420E steel plate to withstand large loads and impact forces, and is not prone to brittle fracture.

Q420D high strength steel plate

Q420D steel plate, as a low-alloy high-strength structural steel, has won a high reputation in the manufacturing industry for its excellent performance and wide application fields. The "Q" in the name of this steel plate represents the yield strength of the steel, "420" is the specific expression of its yield strength value, the unit is MPa, and "D" represents the impact temperature and quality grade of the steel plate, which belongs to D grade and can withstand low temperature impact of -20℃.

Q420C high strength steel plate

Q420C steel plate is a low-alloy high-strength structural steel plate with high strength, good plasticity and toughness, and excellent welding performance. Its yield strength is as high as 420N/mm[gf]b2[/gf], which is much higher than that of ordinary steel, making it perform well when subjected to large loads. At the same time, Q420C steel plate also has high toughness and low brittle transition temperature, and can maintain stable performance in extreme environments. In addition, it also has good cold forming and welding properties, which is convenient for processing and installation.

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.
