Why is the stainless steel faucet rusty? How to avoid rust of stainless steel faucet?

It is not easy for many consumers to buy a house, and it is even more difficult to renovate a house, so happy to move in! Two years have passed since the comfortable days, and the faucet is rusty. "Why did the faucet I bought in a specialty store with so much money get rusty?" So he immediately went to the bathroom store and said, "There is a problem with your faucet." The bathroom store is also very wronged. This is a genuine stainless steel faucet. How can it get rusty? Today we will understand why the stainless steel faucet also rusts? How to avoid rust of stainless steel faucet?



Why is the stainless steel faucet rusty?

When brown rust spots (spots) appeared on the surface of stainless steel pipes, people were surprised: "Stainless steel does not rust, and rust is not stainless steel. It may be that there is a problem with the steel." In fact, this is a one-sided misconception about 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, non-corrosion, and it also has the ability to corrode in media containing acid, alkali, and salt---that is, corrosion resistance. However, the size of its anti-corrosion ability varies with the chemical composition of the steel itself, the state of mutual addition, the conditions of use and the type of environmental media. Such as 304 steel pipe, in a dry and clean atmosphere, it has absolutely excellent anti-corrosion ability, but when it is moved to the seaside area, it will quickly rust in the sea fog containing a lot of salt; while 316 steel pipe has performance good. Therefore, it is not any kind of stainless steel, which is corrosion-resistant and does not rust in any environment.



How to avoid rust of stainless steel faucet?

To ensure that the metal surface is permanently bright and not corroded, it is recommended:

1. The surface of decorative stainless steel must be cleaned and scrubbed frequently to remove attachments and eliminate external factors that cause modification.

2. 316 stainless steel should be used in seaside areas, 316 material can resist seawater corrosion.

3. The chemical composition of some stainless steel pipes on the market cannot meet the corresponding national standards and cannot meet the material requirements of 304. Therefore, rust will also be caused, which requires users to carefully choose products from reputable manufacturers.
