Our company was founded in 2000, which initially committed to providing high-quality steel A588 grade B structural steel plate products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export A588 grade B structural steel plate steel to the international market, opening up the international steel market.
Q345 is a steel material. It is a low alloy steel (C < 0.2%), with good comprehensive properties, low temperature properties, cold stamping properties, A588 grade B structural steel plate welding properties and machinability. Q345 steel is subdivided into Q345A, Q345B, Q345C, Q345D and Q345E. This is the grade distinction, which represents that the impact temperature is different! Q345A, no impact; Q345B, impact at 20 degrees normal temperature; Q345C, impact at 0 degrees; Q345D, impact at - 20 degrees; Q345E, impact at - 40 degrees. At different impact temperature, the impact value is different.
In the face of domestic and foreign steel situation, based on the advantages of production and inventory, we have established our own processing center, and our manufacturing includes different types. Steel A588 grade B structural steel plate surface treatment - such as steel pretreatment (shot peening and shop primer), steel galvanizing; steel structure processing - such as cutting, drilling, milling, turning, bending, welding, etc.
The company has passed ISO quality management system certification, domestic advanced production technology, and high product batch stability. Selected materials, the source controls every quality link to ensure A588 grade B structural steel plate product high quality. Use automated, scientific and systematic manufacturing processes to meet the different needs of customers. Become an excellent domestic steel plate manufacturer, serving customers all over the world.
20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. A588 grade B structural steel plate, 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel A588 grade B structural steel plate plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
