Material common grades: Q235B,Q345B, AB EH32, AB DH36, AB EH36, A588 grade A heavy plate, CCS-A, CCS-B,CCSA, CCSB, CCS,CCSD, CCSE. Carbon structural steel plates and sheets are mainly used in the manufacturing of mechanical parts with complex shapes and high requirements for mechanical properties, but it is difficult to shape them by forging and pressing in the process, such as the gearbox shell of the automobile, the coupler and coupling of the locomotive and vehicle.
A36 is American Standard ASTM material, SS400 is Japanese Standard JIS g3101 steel material for general structure, Q235 is Chinese standard GB700 material. The limitation of the content of the Mn element differs depending on the thickness of the A36 steel plate, and the A36 steel plate of 20 mm or less does not contain Mn. The A588 grade A heavy plate, Q235 steel plate has requirements for the contents of C, Si, Mn, S, P and other elements. But SS400 steel plate only requires S and P to be less than 0.050, and no other element requirements.
After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
