Corrosion of Stainless Steel Plate

1. The surface of the stainless steel plate covered by dust containing metal elements. They are form a micro battery in the moist air, which triggers an electrochemical reaction, which damaged protective film of plate. That is electrochemical corrosion.

2. The organic juice on the stainless steel plate will form organic acid in the water and oxygen, which will corrode the stainless steel plate for a long time.

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

4. In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, and nitrogen oxide), contact with condensed water will form sulfuric acid, nitric acid, and acetic acid liquid spots, causing chemical corrosion. The above can damage to the protective film on the surface of stainless steel plate which cause to corrosion.
