Summary of the causes of rusting of stainless steel hexagonal bars

1. Stainless steel hexagonal rods In the humid air, rare metal particles adhere to the condensed water of the stainless steel hexagonal rod surface layer, and the two form a micro-electric region, causing electric shock chemical reaction, the protective film is damaged and rusted, and the electrochemical corrosion is rusted.

2. The surface of the stainless steel hexagonal rod adheres to the organic juice (such as melon, noodle soup, juice, etc.), and forms an organic acid under the action of water and oxygen. The corrosion of the metal surface caused by long-term organic acid causes rust.

3. The surface of the stainless steel hexagonal bar is filled with acid, alkali and salt substances (such as alkali, water stone ash and glue splashing on the wall), causing local corrosion and rust.

4. In the polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, nitrogen oxide), in the case of condensed water, the surface of sulfuric acid, nitric acid and acetic acid is formed to adhere to the surface, causing chemical corrosion and rust.
