Corrosion conditions of 201 stainless steel plates:
1. the surface of 201 stainless steel is covered by dust with other metal particles or attachments of heterogeneous metal particles.
In humid air, the condensate between the adhesives and 201 stainless steel connects them into a microcell, which triggers an electrochemical reaction and damages the protective film. It is called electrochemical corrosion.
2. 201 stainless steel surface adheres to organic juices, such as melon and vegetable, noodle soup, sputum, etc.. Under water and oxygen conditions, organic acids form and corrode metal surfaces for a long time.
3. 201 stainless steel surface adheres to acid, alkali and salt substances, such as alkali water and lime water spray for wall decoration splash, causing localized corrosion.
4. In polluted air, such as atmosphere containing a large number of sulfides, carbon monoxide, nitric oxide. When encountering condensate, form sulfuric acid, nitric acid, acetic acid liquid point, causing chemical corrosion of 201 stainless steel plate.
All above factors can cause rust on the surface of 201 stainless steel.
