BEBON is a large steel group with finance department, production department, sales team, technical department, quality control department, logistics department and after-sales service team. We are committed to creating a various culture system with its own characteristics, and work hard to create a first-class steel plate company in China. Based on the business philosophy of quality-oriented and strengthened management, the company continues to develop in this industry.
For Q345B steel plate, Q stands for the yield of Q345B material. The 345 at the back refers to the yield value of Q345B material, which is about 345MPa. The yield value will decrease with the increase of Q345B steel plate thickness. Q345B steel plate has good comprehensive performance, low temperature performance, cold stamping performance, welding performance and machinability. It a 573 gr 70 carbon-manganese-silicon steel is widely used in bridges, vehicles, ships, buildings, pressure vessels, etc.
According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for a 573 gr 70 carbon-manganese-silicon steel, 42CrMo steel is quenching and tempering.
After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
