Under normal circumstances, stainless steel faucets will not rust. But if used or maintained improperly, or if the environment where the stainless steel faucet is located is too harsh, it is possible for the stainless steel faucet to rust. When we see yellow or orange rust spots on the surface of steel, we can quickly confirm that they are signs of rust.

A stainless steel faucet is a crystal solid composed of atoms arranged in a manner similar to a patchwork toy. In addition to iron, it also contains its metallic components such as chromium, nickel, titanium, etc. Chromium and nickel elements have anti rust properties, forming a protective film - a passive film - to prevent stainless steel faucets from rusting.


In general, as long as this film is not damaged, ruptured, or contaminated by impurities, stainless steel faucets will not rust. However, if improper use or maintenance causes damage to the passive film, the stainless steel faucet will rust.
