SA588 Grade K low alloy steel plate,The method of distinguishing manganese plate from common carbon steel plate, SA588 Grade K low alloy steel plate is as follows:
(1) Check the spray label
Whether it is manganese plate or common carbon steel plate, it has its own factory spray mark, just check it;
(2)Listen to the cutting sound
The cutting sound of manganese plate is relatively clear and crisp, while that of common carbon steel plate is not clear and crisp, and the manganese plate will fall off as soon as it is cut;
(3) Look at the polishing sparks
Look at the amount of sparks on the surface during polishing. The more sparks and forks are manganese plates, and the lesser ones are common carbon steel plates;
(4) Check the material certificate
Generally, the material certificate will clearly indicate what material it is, just check it.

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 is widely used in bridges, vehicles, ships, buildings, pressure vessels, etc.

Most common steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled steel plates.
