The surface of the stainless steel hinge contains acids, alkalis, and salts, causing local corrosion. Organic material juice adheres to the surface of the stainless steel hinge. In the presence of water and oxygen, it forms an organic acid, which will corrode the metal surface for a long time. In contaminated air, when it encounters condensed water, it forms sulfuric acid and acetic acid liquid spots, causing chemical corrosion.

The surface of the stainless steel hinge has deposits of dust or other metal particles containing other metal elements. In humid air, the condensate between the deposits and the stainless steel connects the two into a micro battery, which initiates an electrochemical reaction The protective film is damaged, which is called electrochemical corrosion.
