Reasons for Rust of Stainless Steel Valves and Solution for Anti-rust

I. Reasons for Rust of Stainless Steel Valves

To test whether stainless steel valves will rust, we can put the same valves in different environments to verify and compare. Generally speaking, if stainless steel valves are placed in relatively dry environments, after long time, the valves are not only as good as new, but also not rusty. But if the valves are placed in seawater containing a lot of salt, they will rust in a few days. Therefore, the corrosion resistance and stainless of stainless steel valves also need to be limited by the use environment. In addition, from the characteristics of stainless steel valve itself, it is stainless because there is a layer of chromium-rich oxide film on its surface to prevent particles such as oxygen atoms from invading and damaging objects, which makes it stainless. But when the film is destroyed by environmental factors, as oxygen atoms enter and iron ions free, stainless steel valve will produce rust.
