DESCRIPTION of 443 Stainless Steel sheet Cold rolled finish

443 Stainless Steel sheet Cold rolled finish There are many forms of damage to the surface film. The following are more common in daily life:

1.443 Stainless Steel sheet Cold rolled finish There are dusts containing other metal elements or attachments of foreign metal particles on the surface. In moist air, the attachments and the condensed water between the stainless steel plate connect the two to form a micro battery. An electrochemical reaction is triggered and the protective film is destroyed, which is called electrochemical corrosion.

2.443 Stainless Steel sheet Cold rolled finish The surface of the plate adheres to the organic juice (such as melon, vegetable, noodle soup, sputum, etc.), which forms organic acid in the presence of water and oxygen, and the organic acid will corrode the metal surface for a long time.

3.443 Stainless Steel sheet Cold rolled finish The surface adhesion contains acid, alkali, and salt substances (such as alkali water and lime water splashing on the decoration wall), causing local corrosion.

4. In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, and nitrogen oxide), it will form sulfuric acid, nitric acid, and acetic acid liquid spots when encountering condensed water, causing chemical corrosion.
