Product Description
Q345B Seamless Square Tubing It is a low carbon alloy steel (c <0.2%), good overall performance, good low temperature performance, cold stamping performance, welding performance and machinability. Widely used in bridges, vehicles, ships, construction, pressure vessels and so on. Q represents the yield of this material, followed by 345, refers to the yield value of this material, at 345MPa or so. And will increase with the thickness of the material to reduce its yield value.
