In what environment is stainless steel plate easily corroded?

The application fields of stainless steel plates are very wide, so how to maintain stainless steel plates to make them more durable?

1. Dust containing other metal elements or attachments of heterogeneous metal particles accumulate on the surface of the stainless steel plate. In the humid air, the condensed water between the attachments and the stainless steel plate connects the two into a micro-battery, causing an electric shock. Chemical reaction destroys the protective film, which is electrochemical corrosion.

2. Organic juice (such as vegetables, noodle soup, phlegm, etc.) adheres to the surface of the stainless steel plate. In the presence of water and oxygen, it forms organic acid. For a long time, the organic acid corrodes the metal surface.

3. The surface of the stainless steel plate contains acid, alkali, and salt substances (such as alkaline water and lime water splash on the wall decoration), causing local corrosion.

4. In polluted air (such as an atmosphere containing a large amount of sulfides, carbon oxides, and nitrogen oxides), when encountering condensed water, sulfuric acid, nitric acid, and acetic acid liquid points will form, causing chemical corrosion.

Many people have a misunderstanding that stainless steel plates are more durable than iron plates, so they don't pay much attention to the maintenance of stainless steel plates. In fact, whether it is stainless steel or other more advanced materials, there will always be its nemesis, but they are not common. Therefore, in order to make the stainless steel plate durable, everyone still needs to pay attention to the above 4 points.
