How to choose the A573 Gr 70 carbon steel sheet? Take 304 material as an example: From the perspective of price analysis, it is assumed that 304 stainless steel pipe is even lower than the general price of 301 material on the market and should be carefully identified. It is likely that other materials are fake. Confess whether the 304 stainless steel pipe is printed with 304 material on the surface and require the manufacturer’s quality certificate as a certificate; it can be tested with acid reagents.
The wear-resistant layer of A573 Gr 70 carbon steel sheet wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy A573 Gr 70 carbon steel sheet carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.
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 Gr 70 carbon steel sheet, 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.
