Chemical Reaction Between Stainless Steel Tee And Oxygen

All metal materials react chemically with oxygen in the air to produce an air oxidation film on the surface layer. Unfortunately, the iron oxide produced on ordinary carbon steel is oxidized again by air, causing the rust corrosion phenomenon to continue to expand and eventually produce holes. The surface layer of ss 304 tee can also be protected by electroplating with paint or air oxidation-resistant metal materials (such as zinc, nickel and chromium), but, as people know, this protection is only a film. If the protective layer is damaged, the ss reducing tee below will begin to rust.
