Stainless steel magnetic pumps also rust?

2019/08/26

A thin layer of magnetic pump stainless steel on the surface of the formation and the stability of the fine solid chromium rich oxide film (protective film), to prevent the infiltration of oxygen atoms, to oxidation, and the ability to obtain anti-corrosion. Once there are some reasons, the thin film is constantly damaged. The oxygen atoms in air or liquid will continuously infiltrate or the iron atoms in the metal will continuously separate out, forming loose iron oxide, and the metal surface will also be corroded constantly.

Therefore, it is not the stainless steel magnetic pump itself will corrode, the cause of corrosion of the stainless steel magnetic pump is a lot of:

1, stainless steel pump surface deposited dust or heterogeneous metal particles containing other metal elements of the attachment, in the humid air, condensed water and adhesion between the stainless steel, the two together into a micro battery, causing the electrochemical reaction, the film has been destroyed, called electrochemical corrosion.

2, the surface of the stainless steel magnetic pump adheres to the acid, alkali and salt materials (such as alkali water and lime water splashing), causing local corrosion.

3, in the air contains a large number of chlorine medium, such as salt, sulfuric acid, hydrochloric acid, oxalic acid, detergent or alkali, such as cement and other impurities, it will make the surface protective film corroded and destroy, resulting in the corrosion of magnetic pump.

Of course, the use of less than 304 material requirements of stainless steel to produce stainless steel magnetic pump, is also a cause of the pump rust.
