Hot rolled a573 grade 65 [450] plates How to distinguish the inferior steel plate?

Wear resistant steel plate a573 grade 65 [450] plates is an important material for industrial application. The traditional wear resistant steel is the high manganese steel which hardens under the impact load. The premise of its function must be subjected to enough impact load. With the development of wear resistant steel technology, NM series steel plate breaks through the limitation of traditional high manganese steel and realizes the application space of wear-resistant steel. The main a573 grade 65 [450] plates grades of NM series wear resistant steel plates are NM360, NM400, NM450, NM500, NM550, NM600.

How to distinguish the inferior steel plate?
1. The surface of the fake and inferior steel plate is easy to produce scab. 2. The material of fake and inferior steel plate is not uniform and there are many impurities. The surface of fake and inferior steel plate is often pitted. Pitting is an irregular and uneven defect on the surface of a573 grade 65 [450] plates, steel plate caused by serious wear of rolling groove. Due to the pursuit of profit by the manufacturers of fake and inferior steel plates, the groove rolling often exceeds the standard.

In the welding process, effectively preventing the stress and deformation of the component during the welding process is the key to ensuring the welding quality of the wear-resistant steel plate. In the welding process, after spot welding each part according to the position of the drawing, ensure that the size is consistent with the drawing. The welding method of symmetrical multi-layer multi-pass welding is adopted to ensure the appropriate welding process parameters, which can effectively prevent the welding deformation of the a573 grade 65 [450] plates, wear-resistant steel plate.
