Stainless steel flanges are more important devices used in the construction industry, and many constructions cannot be carried out without stainless steel flanges. So what are the characteristics of stainless steel flanges? Next, let's take a closer look.
All metals react with oxygen in the atmosphere to form an oxide film on the surface. Unfortunately, the iron oxide formed on ordinary carbon steel continues to oxidize, causing the corrosion to continue to expand and eventually form holes. Stainless steel flanges can be plated with paint or oxidation-resistant metals (for example, zinc, nickel, and chromium) to ensure the surface of carbon steel, but, as is known, this protection is only a thin film. If the protective layer is damaged, the steel below will begin to corrode, resistant to weak corrosive media such as air, steam, water, and chemically corrosive media such as acids, alkalis, and salts. Also known as stainless acid-resistant steel. In practical applications, steel that is resistant to corrosion by weakly corrosive media is often called stainless steel flange, and steel that is resistant to corrosion by chemical media is called acid-resistant steel. Due to the difference in chemical composition of the two, the former is not necessarily resistant to chemical media corrosion, while the latter are generally stainless. According to these characteristics of stainless steel flanges, we must do a good job of anti-corrosion work of stainless steel flanges, which is to ensure that its function is carried out normally.
