       Stainless steel screw is the daily life of the common fasteners, in use process, rust is a common phenomenon, it will not only affect the appearance, also will affect the use of the properties of stainless steel screws. Therefore we must pay attention to the use of the main points in the process of using stainless steel screws.

1, or dust particles heterogeneous metal attachments, in the humid air, condensation water fixtures and stainless steel screws, and the two together into a micro battery, causing the electrochemical reaction, the protective film is damaged, termed the electrochemical corrosion.

2, stainless steel screw surface adhesion of organic juice (such as vegetables, soup, sputum), in the case of water oxygen to form organic acid, organic acids are long on the surface of metal corrosion.

3, stainless steel surface adhesion containing acid, alkali, salt material (such as wall decoration, stone alkaline ash water splash), caused by partial inhibition.

In 4, there are 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.
