Why Is Stainless Steel Wire Mesh Rusting?
As a Stainless-steel Wire Mesh Supplier, there are some details to show to you. When brownish corrosion areas (dot) appeared on the surface of stainless-steel pipes, people were amazed: "Stainless-steel is not rusted, corrosion is not stainless steel, and also there may be problems with steel." Actually, this is a one-sided misunderstanding regarding the lack of understanding of stainless steel. Stainless-steel mesh belts will certainly also corrosion under specific conditions.
Stainless-steel has the capacity to stand up to climatic oxidation - that is, rust, as well as also has the capacity to rust in acids, alkalis, and salts - that is deterioration resistance. However, the degree of deterioration resistance differs with the chemical composition of the steel itself, the state of communication, the conditions of use, and also the type of environmental tool. As an example, a 304 steel pipe has definitely exceptional corrosion resistance in a completely dry and clean atmosphere, but it is relocated to the coastal area, and it will certainly quickly corrosion in sea haze consisting of a lot of salt; while 316 steel pipeline will carry out. excellent. Therefore, it is not any sort of stainless steel, it can resist rust and rust in any kind of environment.
Fine Stainless-steel Wire Mesh is a layer of extremely thin, secure, and fine-grained material that remains to go into and continue to oxidize, and also attains the ability to resist corrosion. Once there is some factor, the film is ruined once in a while, air or liquid will certainly get in every so often or the iron atoms in the metal will certainly be separated periodically, developing loosened oxygen and also rusting. For that reason, the stainless-steel mesh does temporarily rust, as long as we do the correct cleaning and maintenance work for a long time, it works to include item life, greatly reduce the damage price, and then minimize the expense of item replacement.
Stainless steel is a really slim as well as strong and stable chromium-rich oxide movie (safety movie) based on the surface area to stop the oxygen atoms from remaining to penetrate and remain to oxidize, therefore getting the capability to resist corrosion. When for some reason, the film is continually destroyed, oxygen atoms in the air or liquid are continually penetrated or iron atoms in the steel are constantly divided to develop loose iron oxide, and the surface area of the steel is continually rusted. This sort of surface area film is damaged in several types, and the adhering to are common in life:
1. The surface area of the stainless steel mesh belt includes dust or various other metal particles connected to other metal elements. In the moist air, the condensed water between the attached material as well as the stainless steel links the two into a mini battery, triggering electrical energy. In the chain reaction, the protective film is ruined, which is called electrochemical corrosion.
2. The surface area of the stainless steel adheres to the natural juice (such as melon, noodle soup, glutinous rice, and so on), and also in the case of water and also oxygen, it constitutes a natural acid, and also the natural acid wears away the steel surface area for a very long time.
3. The surface area of the stainless-steel sticks to acid, alkali, and also salt substances (such as alkali water and rock water sprinkling on the wall), triggering local corrosion.
4. In contaminated air (such as the ambiance containing a big amount of sulfide, carbon oxide, nitrogen oxide), when it comes to condensed water, sulfuric acid, nitric acid, the acetic acid fluid point is created, creating chemical deterioration.
