Hot Rolled EN steel grade S275JR plates Boiler Steel

Wear resistant steel plate EN steel grade S275JR plates is widely used in engineering, mining, construction, agriculture, cement production, port, electric power, metallurgy and other mechanical products, which require high strength and wear resistance. Such as bulldozers, loaders, excavators, dump trucks and various mining machinery, grab, stacker reclaimer, conveying bending structure, etc. The wear resistant steel plate EN steel grade S275JR plates can obtain good combination of strength and toughness through scientific quenching and tempering process, which can also improve the steel hardness to achieve the purpose of wear resistantance.

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 EN steel grade S275JR plates is widely used in bridges, vehicles, ships, buildings, pressure vessels, etc.

The preparation of EN steel grade S275JR plates galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for EN steel grade S275JR plates centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
