Q370q steel is a kind of bridge steel plate. It is delivered in hot rolled, normalized condition. There are three quality levels Q370qC, Q370qD, and Q370qE. Bridge steel Q370qC, Q370qD, A572 Gr 55 CS steel carbon plate and Q370qE steel plates have different impact temperatures: C represents 0℃, D represents -20 ℃, and E represents -40℃. Q370qC-Z25 steel plate can be hot-rolled and normalized heat-treated. When mechanical properties are required, large thickness must be normalized. The thickness of Q370q steel plate we supply is above 8mm.
The company adheres to the A572 Gr 55 CS steel carbon plate business tenet of "integrity casting strength, cooperation creating win-win", takes value-added service of supply chain as the tenet, and under the premise of existing market, bulk trade, logistics distribution and other advantages, develops a new comprehensive steel industry model combined with informatization. And will continue to provide customers with high-quality steel products and good service. We sincerely welcome new and old customers to join hands with our company A572 Gr 55 CS steel carbon plate and seek common development!
After twenty years of efforts, the company has completed the steel plates production process and complete testing equipment from smelting, rolling, drawing, heat treatment to A572 Gr 55 CS steel carbon plate full material. Large-scale production, intensive, and unremitting research and development and innovation make our products maintain long-term vitality. In early 2008, the company established the Ministry of foreign trade, and our A572 Gr 55 CS steel carbon plate steel plate products are now exported to the South Asia, the Middle East, Europe and the United States.
The performance of heat treatment process reflects the difficulty of heat treatment and the tendency of defects of the steel. It mainly includes hardenability, superheat sensitivity, temper embrittlement tendency and oxidation decarburization tendency. The hardenability of A572 Gr 55 CS steel carbon plate, alloy steel is high. The cooling method can be used slowly during quenching, which can reduce the deformation and cracking tendency of the workpiece. The addition of Mn and Si will increase the superheat sensitivity of steel. The strengthening effect of alloy elements on steel in quenching and tempering state is the most significant.
Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
