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 A573 Grade 70 carbon structural steel raw material is widely used in bridges, vehicles, ships, buildings, pressure vessels, etc.

BBN company has implemented a resource strategy combining global resource procurement, domestic resource unified purchase, and joint purchase and distribution. It has maintained good relations of cooperation with more than 100 domestic and foreign steel mills, and can purchase low-quality and high-quality steel futures in all directions and through multiple channels. The company can grasp the specifications and quantities of the spot resources of major steel mills in real time, and can timely and quickly meet customer demand for steel spot resources.

Magnetic particle flaw detection is only suitable for detecting surface defects, which means that by laying magnetic powder on the surface of the equipment and using its aggregate shape on the surface defects of the magnetic material equipment to determine the position, size and shape of the defect. This A573 Grade 70 carbon structural steel raw material method has a relatively low cost and is easy for steel production enterprises to adopt in batches. However, for special steel profiles with deeper thickness, whether this method is used to detect hidden defects is yet to be verified.
