What are the factors to be aware of when choosing a stainless steel wire mesh screen?
When selecting stainless steel wire mesh screen in a corrosive environment, in addition to a detailed understanding of the specific conditions of use of stainless steel, the main factors to be considered are the corrosion resistance strength, toughness and physical properties of stainless steel wire mesh screen, processing,forming properties, resources, price and availability. The corrosion resistance of stainless steel wire mesh screen includes the properties of stainless steel and acid-resistant, alkali, salt and other corrosive media as well as resistance to oxidation, vulcanization and oxidation at high temperatures. Since different stainless steel wire mesh screen are mainly used to solve various corrosion problems encountered in actual engineering, the corrosion resistance of stainless steel wire mesh screen in a corrosive environment is the first consideration for the material selection personnel. Corrosion is the damage caused by chemical or electrochemical interaction between metal and medium, and corrosion resistance refers to the ability of stainless steel wire mesh screen to resist corrosion damage. Therefore, when selecting corrosion resistance in material selection, you need to pay attention to the following points:
1. The standard of corrosion resistance is artificially determined. it needs to be recognized 、used、and not subject by us. The specific criteria for corrosion resistance should be determined according to the specific application requirements.
2. Corrosion resistance is relative and conditional.
It is often said that the stainless steel's rust and corrosion resistance are relative to rust and non-corrosion. It means that under certain conditions (medium, concentration temperature, impurities, pressure, flow rate, etc. - timing) stainless steel does not Rust and corrosion resistance. So far, there is no stainless steel with corrosion resistance and corrosion resistance in any corrosive environment. Therefore, the material selection (purchasing) personnel must be selected according to the specific conditions of use. After the stainless steel grade is selected, The use department also needs to know the correct way to use stainless steel so that stainless steel can achieve corrosion resistance.
3. Select stainless steel to consider its resistance to general corrosion, but also to its local corrosion resistance.
In some aqueous and chemical media, the latter needs more attention.
4. When applying the corrosion resistance data of stainless steel in various manuals, it should be noted that many of the data are only the test results in some experiments, and often have a large difference with the actual media environment.
5. If stainless steel equipment and components fail due to corrosion, the cause of corrosion damage should be analyzed, and measures should be taken after the cause is identified, and should not be thrown away.
