Stainless steel is a very thin layer formed on the surface of the solid stability of dense chromium-rich oxide film (protective film), to prevent the infiltration of oxygen atoms, to oxidation, and the ability to obtain anti-corrosion.
If for some reason, this film was constantly undermined, air or liquid oxygen atoms will continue to infiltrate or metal atoms of iron to keep out from it, the loose formation of iron oxide, metal surface is subject to constant corrosion.
Many of these surface damage in the form of daily life, many are as follows:
1 stainless steel surface deposited dust or heterogeneous metal particles containing other metal elements of attachment, in the moist air, water and attachment of stainless steel, and the two together into a micro cell, causing the electrochemical reaction, the protective film is damaged, called electrochemical corrosion.
2 stainless steel surface adhesion of organic juice (such as vegetables, soup, sputum), in the case of water oxygen, organic acid, long time organic acid on the surface of metal corrosion.
3 stainless steel surface adhesion containing acid, alkali, salt material (such as wall decoration of alkaline water, lime water splash), caused by the localized corrosion.
4 in air pollution (such as containing a large amount of sulfide, carbon dioxide, nitrogen oxide atmosphere), meets the condensed water to form sulfuric acid, nitric acid, acetic acid, liquid, caused by chemical corrosion.
