Stainless steel does not mean it will never rust.
In our daily life, do you always doubt that whether i am cheated by the seller for why my stainless faucet get rust!!!today，let me tell you the truth.
The corrosion resistance of stainless steel is 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 not easy to rust steel, but there are not any steel which will never getting rust.
The test results show that the corrosion resistance of steel increases with the increase of chromium content in the weak medium such as atmosphere and water and the oxidation medium such as nitric acid. When the chromium content reaches a certain ratio, the corrosion resistance of the steel may be abrupt, that is, Steel is also easy to rust and not resistant to corrosion any more.
When brown rust spots appear on the surface of stainless steel tubes, the most surprising thing is that “stainless steel is not rusted, and rusted stainless steel is not stainless steel, which may be a problem with 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 a medium such as acid, alkali or salt, that is, corrosion resistance. However, the corrosion resistance of steel varies depending on its chemical composition, mutual phase of use, conditions of use, and type of environmental media.
So, do you know why stainless steel faucets are also rusting?
Stainless steel is a healthy material that is lead-free and resistant to acids, alkalis, corrosion, and harmful substances. It can ensure human health and hygiene.Stainless steel faucets are safe, lead-free, free from corrosion and exudates, and have no odor or turbidity. It will not cause secondary pollution to water ， keep water clean and hygienic, and ensure complete safety and safety.
In fact, at present, the market is still more popular copper basin faucet, the price is in the middle and high-end market. Stainless steel taps take longer to use than copper faucets. Of course, the price will be more expensive. So it is no need to worried about this question.
