The application of laser processing technology in processing of hardness of SMA490CW corten steel sheet

Preheating cutting: The most effective way to prevent steel plate cutting cracks is to preheat before cutting. Before flame cutting, the steel plate is usually preheated, and the preheating temperature mainly depends on the quality level and thickness of the steel plate. The preheating method can be carried out with flame burner, electronic heating pad, or heating furnace. In order to determine the preheating effect of the steel plate, the required temperature should be tested at the heating point.

The wear-resistant layer of hardness of SMA490CW corten 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 hardness of SMA490CW corten steel sheet carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our hardness of SMA490CW corten steel sheet products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
