Mn content in the SA588 Grade B structural steel material

Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;

The metal structure of 15CrMo steel is martensite. This material has good oxidation resistance at about 650℃, good thermal strength below 600 ℃, and good shock absorption and thermal conductivity. SA588 Grade B structural steel material, 15CrMo steel is widely used in steam turbines. However, this type of steel has a greater tendency to harden and has poor welding performance. GB/T 3077-2015 15CrMo plates are supplied with 5 to 70MM thick, can be set to roll futures.

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 SA588 Grade B structural steel material is widely used in bridges, vehicles, ships, buildings, pressure vessels, etc.
