Are stainless steel valves really rustless?

Temps: 2022-06-21 Accessos : 10

Generally speaking, stainless steel is considered to be not easy to rust, but in fact, stainless steel will also rust. Stainless steel's rust resistance and corrosion resistance are due to the formation of chromium rich oxide film (passive film) on its surface. The rust resistance and corrosion resistance are relative.
To detect whether stainless steel valves can rust, the same valve can be placed in different environments for verification and comparison.
Under normal circumstances, if the stainless steel valve is placed in a relatively dry environment, after a long time, the valve is not only as good as new, but also without rust.
If the valve is placed in seawater containing a lot of salt, it will rust in a few days. Therefore, the corrosion resistance and stainless steel property of stainless steel valves also need to be measured according to the environment.
So, if the stainless steel valve is rusty, how should users solve this problem?    
First, the surface of stainless steel valves should be cleaned and scrubbed frequently to remove attachments and external factors that cause corrosion.
Second, 316 stainless steel should be used in coastal areas, because 316 material can resist the corrosion of seawater.
Third, the chemical composition of some stainless steel pipes on the market does not meet the corresponding national standards, which can not meet the material requirements of 304, so it will also cause rust. In this regard, the technicians said that when users choose stainless steel valves, they must carefully select the products of reputable manufacturers.
