Stainless steel how conserve?

Stainless steel is to rely on its appearance to form a paper-thin and consolidate close stable Fu Ge oxidizes film (defend velar) , avoid oxygen atomic to be entered continuously, oxidize continuously, and obtain fight rustily ability. Once have some kind of reason, this kind of film sufferred damage ceaselessly, atom of the oxygen in air or liquid can be entered ceaselessly or the iron in the metal is atomic ceaselessly analyse leaves come out, form loose ferric oxide, metallic appearance also suffers ceaselessly rustily. The kind that this kind of outside film damages a lot of.

Often see more in the day have a few kinds as follows:

Appearance of 1. stainless steel retains the attachment that accumulating the dust that contains a lot ofother tantalum or alien metal grain, in humid air, the condenser water between attachment and stainless steel, become both a small cell repeatedly, caused electrochemistry echo, diaphragm suffers damage, say call electrochemistry is corroded.

Conglutinate of appearance of 2. stainless steel has machine content juice (the dish that be like melon, water in which noodles have been boiled, phlegmy wait for) , below state of oxygen having water, make organic acid, long-term an organic acid is outside to the metal corrode.

Conglutinate of appearance of 3. stainless steel contains a lot ofacerbity, alkaline, salt kind material (if decorate) of splash of the buck of wall, limewater, cause a part to corrode.

4. is in the air that has pollution (if contain a lot ofthe atmosphere) of nitrogen of carbon of a large number of sulfide, oxidation, oxidation, treat condenser water, make point of fluid of vitriolic, nitric acid, acetic acid, cause chemistry to corrode. Above state all can form stainless steel appearance to defend velar attaint is caused rustily. So, belong to outside and perpetual light for bail, not by rustily.
