Why do stainless steel faucets rust?

I believe that many families have had such an experience. They spent a lot of money in specialty stores to buy genuine stainless steel faucets that are not cheap. After a year or two, they found that the faucet at home was rusted. Why did it rust so quickly? And there will be water taps ticking and leaking?

This confuses consumers. They all think that there is a problem with the quality of the faucet, so they will ask the merchant for after-sales compensation. Many times, bathroom sales stores also feel wronged. We sell genuine stainless steel faucets, how can they rust? Now let Landonbath help you work out!

Stainless steel faucet doesn't mean it will never rust

The corrosion resistance and corrosion resistance of stainless steel are due to the formation of a chromium-rich oxide film (passivation film) on its surface. This stainless steel and corrosion resistance are relative. In layman's terms, stainless steel is steel that is not easy to rust and rust, not steel that does not rust.

The test results show that the corrosion resistance of steel increases with the increase of chromium content in weak media such as air and water and in oxidizing media such as nitric acid. When the chromium content reaches a certain proportion, the corrosion resistance of steel will change abruptly, that is, from easy to rust to not easy to rust, from no corrosion resistance to corrosion resistance.

When brown rust spots appear on the surface of stainless steel pipes, people are most surprised that "stainless steel does not rust, it is not stainless steel that rusts, it may be a problem with the steel".

In fact, this is a one-sided misunderstanding of the lack of understanding of stainless steel. Stainless steel can also rust under certain conditions. Stainless steel has the ability to resist atmospheric oxidation, that is, rust, and also has the ability to corrode in acids, alkalis, salts and other media, that is, corrosion resistance. However, the corrosion resistance of steel varies depending on its chemical composition, additive state, service conditions, and type of environmental media.

So, do you know why stainless steel faucets also rust?
