The company is a leading company that sells A572 grade 42 ms steel coil 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 A572 grade 42 ms steel coil 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.
We are mainly engaged in corrosion-resistant steel materials and steel processing parts, the varieties include A572 grade 42 ms steel coil Q355NHB, Q345NS, 09CuPCrNi-A,coten-A/B,S355J0W, Q345qNHB. The application fields involve landscape gardening, outdoor structure, environmental protection equipment, railway carriage, bridge manufacturing and many other industries. The company currently has many steel extension processing capabilities such as laser cutting, bending, rolling, welding, pipe making, and surface treatment.
Grades A572 grade 42 ms steel coil, Q345 (16Mn) and Q390 steel have good comprehensive mechanical properties, good welding performance, cold and hot workability and corrosion resistance. C, D, E grade steel has good low temperature toughness. Mainly used for ships, boilers, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting and transportation machinery and other higher-load welding structural parts.
Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of A572 grade 42 ms steel coil, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.
S355J2G3 is low alloy high strength structural steel, and it is roughly equivalent to GB Q345D.S355J2G3 is a European standard steel with composition of C ≤ 0.20, Si ≤ 0.55, Mn ≤ 1.60, P ≤ 0.035, S ≤ 0.035. The meaning of J2G3 indicates that the delivery state of S355J2G3 steel is normalized, the impact energy at - 20 ℃ is 27J. G3 and G4 indicate the deoxidization mode. A572 grade 42 ms steel coil, S355J2G3 steel is semi killed steel, S355J2G4 steel is fully killed steel.
It is very important for a company to have a sound after-sales service system, which better guarantees the interests of customers and increases the reliability of the company's products in the hearts of customers. Our company has a dedicated after-sales service team and good after-sales service reputation, and has been recognized by customers over the past decades. Whenever there is problem about our A572 grade 42 ms steel coil steel materials during application on the user site, our after-sales service persons will assist to find solutions at the first time.
