15CrMo alloy plate is a heat-resistant steel with pearlite structure, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperatures, and has a certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in steel, the hardening tendency of QStE340TM automotive steel coil and 15CrMo alloy plate is obvious and the weldability is poor. After welding, local high temperature tempering treatment should be carried out. The heat treatment process of 15CrMo alloy plate is as follows: the temperature rise rate is 200°C/h, the temperature is raised to 715°C for 1 hour and 15 minutes, the temperature drop rate is 100°C/h, and the temperature is reduced to 300°C before air cooling.

WTST 37-3 steel plate is a kind of carbon steel plate. WTST 37-3 steel plate can be used to build low temperature sea water resistant containers. When the customer orders QStE340TM automotive steel coil WTST 37-3 steel plate from us, our factory should roll it in full accordance with SEW 087-2 specification, and the factory will issue the original mill test certificate for inspection before delivery.
