Stainless steel wire why rust?
In polluted air (e.g., atmosphere containing large amounts of sulfides, oxides of carbon and nitrogen oxides), condensate is formed when sulfuric acid, nitric acid, and acetic acid are subjected to condensation, resulting in chemical corrosion.
Stainless steel surface adhesion contains acid, alkali and salt substances (such as decoration wall caustic soda, lime water splash), causing local corrosion.
1. stainless steel 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 electro chemical corrosion.2. stainless steel surface adhesion of organic juice (such as vegetables, soup, sputum), oxygen in the water under the circumstances, a long time, organic acid, organic acid on the surface of metal corrosion
1., the surface of decorative stainless steel must be cleaned and scrubbed frequently, removing attachments and eliminating the external factors that cause modification.2. beach area should use 316 material stainless steel, 316 material can resist seawater corrosion.3., some stainless steel pipe on the market, the chemical composition can not meet the corresponding national standards, less than 304 of the material requirements. Therefore, it will cause rust, which requires users to seriously choose reputable manufacturers of products
