Common medium thick and heavy steel plates are widely used for manufacturing various containers, furnace shells, furnace plates, bridges and automobile static steel plates, low steel alloy steel plates, bridge steel plates, general steel plates, boiler steel plates, pressure vessel steel plates, pattern steel plates, automobile girder steel plates, tractor parts and welding components. A572 Gr 42 ms steel coil, bridge steel plates are used for large railway bridges. They are required to bear dynamic load, impact, vibration, corrosion resistance, etc.
Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, A572 Gr 42 ms steel coil based on a high starting point and high technology, the company has vigorously developed various steel products A572 Gr 42 ms steel coil and deep-processed parts, steel structures, precision castings, seamless pipes.
During the construction of hot-dip A572 Gr 42 ms steel coil galvanized pipe, the correct welding process shall be adopted, the inspection and acceptance shall be carried out in strict accordance with the specification, and the anti-corrosion treatment (zinc rich paint) shall be done timely after the welding is completed. It is feasible in the construction process of open and closed air conditioning system, which can improve the A572 Gr 42 ms steel coil construction speed and the firmness of the pipe connection. Therefore, the hot-dip galvanized pipe can be welded and connected under the construction conditions and on the premise of relevant protection and anti-corrosion measures.
A572 Gr 42 ms steel coil controlled rolling is that, on the basis of adjusting the chemical composition of A572 Gr 42 ms steel coil, by controlling the heating temperature, rolling temperature, deformation system and other process parameters, the change law of austenite structure and the microstructure of phase transformation products are controlled, so as to achieve the purpose of refining the structure and improving the strength and toughness of A572 Gr 42 ms steel coil.
We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards. The most important thing is that we have set up the correct concept of after-sales service, "customer first, sincere service for users".
