Q345B material is a low carbon alloy steel grade with good overall performance, low temperature performance, cold stamping performance, welding performance and machinability. Q345 serues steel is widely used in bridges, vehicles, ships, buildings, pressure vessels. Q represents the yield of this material, and the number 345 refers to the yield value of this material, which is around 345MPa. As the thickness of the material increases, its yield value decreases.

The application of wear-resistant steel plate, S355J2G1W steel for bridge construction is very many, especially in the factory building. In terms of various operation control of wear-resistant steel plate, bending is more difficult to master, which is mainly due to the poor elasticity of the product. Of course, we have corresponding solutions. In order to bend the wear-resistant steel plate more simply and effectively, it is recommended to use hydraulic pipe bender for bending, and the corresponding mold should be equipped with the machine in advance. In this way, the wear-resistant steel plate will not have defects, the quality can be guaranteed, and the use effect will be better.

In 2015, we participated in an tender for oil and casing pipe in Pakistan. Because of our professional service and company strength. The end user chose us as the final contractor of the project of 22000 meters pipes of different sizes production. It takes us about 3 months to produce all the pipes S355J2G1W steel for bridge construction . We use bulk vessel to ship the pipe to Karachi port. Our engineers went to Karachi port to inspect the condition along with the customer when ship arrive. The customer gave high appraise to the pipe quality and our service
