Stainless steel corrosion conditions

1. Stainless steel surface accumulating the attachments contain other metal elements or heterogeneous metal dust particles,
In humid air, condensate and magnets stainless steel fixtures between the two together into a micro-cell, triggering
The electrochemical reaction, the protective film is damaged, call it that electrochemical corrosion.
2. Stainless steel surface adhesion of organic juice (such as vegetables, soup, sputum, etc.), there are circumstances under water, oxygen,
Constitutes organic acids, organic acids prolonged the corrosion on the metal surface.
Alkaline 3. 410 stainless steel plate surface adhesion containing acid, alkali, salts (such as a wall decoration, lime spray
Splash), causing localized corrosion.
4. air pollution (such as with a lot of sulfides, carbon monoxide, nitrogen oxide atmosphere), cold
Condensate water to form sulfuric acid, nitric acid, acetic acid solution point, causing chemical corrosion.
Above may damage the stainless steel surface protection film caused corrosion.
