Let's learn about it with the Butterfly Valve Supplier . Stainless steel butterfly valve will rust during use. Through metallographic analysis, dyeing test, heat treatment test, SEM and other tests, it is found that the key factor for material corrosion is the precipitation of carbides along the grain boundaries to form chromium-depleted areas, which causes the stainless steel butterfly valve to rust. Material CF8M stainless steel butterfly valve rusts during use. After austenitic stainless steel undergoes normal heat treatment, its structure should be austenite at room temperature, and its corrosion resistance is very good. Analyze the cause of butterfly valve corrosion. Butterfly Valve The stainless steel butterfly valve material is nickel-chromium austenitic stainless steel, which is usuall
