Many people buy 316L stainless steel, are that it is strong anti-rust, some people will ask the stainless steel plate will rust, the answer is not necessarily.

Stainless steel surface deposits with other metal elements of dust or heterogeneous metal particles attached to the wet air, between the attachment and stainless steel condensate.

The two together into a micro-battery, triggering the electrochemical reaction, the protective film is damaged, called electrochemical corrosion. 2. Stainless steel surface adhesion of organic juice (such as melons, soup, sputum, etc.), in the case of water and oxygen.

Constitute an organic acid, long time the organic acid on the metal surface corrosion. 3. Stainless steel surface adhesion contains acid, alkali, salt substances (such as decorative walls of alkaline water, lime water splash), causing local corrosion. 4. In contaminated air (eg atmospheric containing large amounts of sulfide, carbon oxide, nitrogen oxide).
