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 heat treatment process can significantly improve the physical properties of steel, improve the compressive strength, ductility and service life of parts, and improve the hardness and wear resistance. Therefore, critical equipment parts and special tools must be quenched and tempered. The quenching and tempering treatment can also improve the production and processing performance of the S460ML plate sheet product workpiece, thereby improving the production efficiency and production processing quality.

On March 17 th 2018, our Sudan customer purchased the SG295 cylinder steel coils through other country such as UAE,Turkey before they cooperate with us. After they research our regular customer in Uganda, UAE, and his friends in China, he is satisfied with our company. Our produced SG295 cylinder steel is mainly used to fabricate low temperature pressure vessels like gas cylinder. The customer is very satisfied to our S460ML plate sheet quality control and professional arrangement for the SG295 steel order.
