Stainless Steel Wire Mesh Can Be Used How Long
Jul 04, 2016

Stainless steel with resistance to atmospheric oxidation---that is, no rust, as well as in the presence of acid, alkali, salt corrosion---that is, in the medium corrosion resistance. Its corrosion resistance is the size of the steel chemical composition, and each state change, conditions of use and the type of environmental media. Such as 304 stainless steel wire mesh, in a clean, dry atmosphere, absolutely excellent corrosion resistance capability, but move it to the coast, contains a lot of salt in sea mist, will soon rust and 316 steel tube is good. So instead of any kind of stainless steel, resistant to corrosion rust in any environment.
Stainless steel depends on its surface to form a layer of very thin but strong fine stable of chromium-rich oxide film (protective film), preventing oxygen atoms continue to infiltrate and oxidation, and resistance to corrosion. If for some reason, this film has been the growing destruction of, air or oxygen atoms in the liquid will become increasingly infiltrate or metal iron atoms on the left and forming loose oxide, corrosion of metal surfaces will be kept. Many forms of damage to the surface film, common in everyday life are the following:
1. stainless steel accumulation on the surface of other metal dust or alien particles is attached, in the humid air, fixtures and stainless steel condensate, connecting them into a micro-cell, triggering chemical reactions, damage the protective film, called electro-chemical corrosion.
2. glue the stainless steel surface organic juices (such as vegetables, noodle soup, phlegm, etc), in case water oxygen to form organic acids and organic acids on corrosion of metal surfaces for a long time.
3. stainless steel adhesive containing acids, alkalis, salts (such as decorating the walls of the soda water and lime water splash) which can cause localized corrosion.
4. where there is pollution in the air (which contain a lot of sulphides, carbon oxide, nitrogen oxides the atmosphere), condensate, forming sulfuric acid, nitric acid, acetic acid, causing corrosion.
The above may result in corrosion of the protective film on stainless steel surface the damage caused. So, in order to ensure permanent light on the metal surface, recommendations not to be rust:
1. decorative stainless steel surfaces must always be scrubbed clean, remove the attachments, remove modification of external factors.
2. coastal areas using 316 stainless steel, 316 material resistant to seawater corrosion.
3. chemical composition of stainless steel tube on the market cannot comply with the appropriate standards, up to 304 material requirements. Can also cause rust, which require the user to carefully select products from reputable manufacturers.
