Stainless steel is a very thin, strong and dense stable chromium-rich oxide film (protective film) formed on the surface to prevent oxygen atoms.

Continue to infiltrate, continue to oxidize, and obtain anti-corrosion energy

force. Once for some reason, the film is constantly destroyed, and oxygen atoms in the air or liquid will continue to infiltrate or gold.

The iron atoms in the genus are continuously separated and form loose oxygen.

With iron, the metal surface is constantly rusted. This surface film is destroyed in many forms.

There are several common occurrences in daily life:

1. The surface of the stainless steel is filled with dust or other metal particles attached to other metal elements, in humid air,

Condensate between the attachment and the stainless steel, connecting the two into one

A micro-battery triggers an electrochemical reaction and the protective film is destroyed, which is called electrochemical corrosion.

2, the surface of the stainless steel adheres to organic juice (such as melon, noodle soup, wolfberry, etc.), in the case of water and oxygen, constitutes organic acid, long-term

The corrosion of the metal surface by organic acids.

3. The surface of stainless steel adheres to acid, alkali and salt substances (such as alkali water and lime water splashing on the wall), causing local corrosion.
.

4. In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, nitrogen oxide), in the case of condensed water, sulfuric acid is formed.

Nitric acid, acetic acid liquid point, causing chemical corrosion. the above
