What Are The Reasons For The Rust On The Stainless Steel Surface?
Jan 14, 2019

   1. Stainless steel in humid air, rare metal particles adhere to the condensed water of the stainless steel surface layer, the two form a micro-electric region, triggering a chemical reaction of electric shock, the protective film is damaged and rusted, and it is electrochemically corroded and rusted.

     2. The surface of the stainless steel adheres to the organic juice (such as melon, noodle soup, juice, etc.), which constitutes 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 stainless steel adheres to 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, sulfuric acid, nitric acid, acetic acid liquid surface is formed, causing chemical corrosion and rust.
