1. In a gas with environmental pollution (such as air with a lot of sulfate, carbon oxide, and nitrogen oxide), it will produce hydrochloric acid, sodium cyanide, and glacial acetic acid liquid spots when encountering condensed water, causing organic chemical erosion.
2. The surface of the stainless steel bolt adheres to the organic compound juice (such as melon, vegetable, noodle soup, sputum, etc.), which forms citric acid under the condition of water and oxygen, and the citric acid will corrode the metal surface for a long time.
3.Smoke or attachments of heterogeneous metal material particles. In the cold and humid gas, the attachment and the condensed water of the stainless steel bolt connect the two to form a micro rechargeable battery, which causes electrochemical corrosion and severe damage to the protective film, which is called The principle of the primary battery.
4. The surface of the stainless steel plate is attached with acid, alkali, and acid salt chemicals (such as edible alkali on the interior decoration wall, splash of lime slurry), causing partial corrosion.
