There are lots of applications for stainless steel sintered mesh, in our life, it can be used as a filter element in various industries to screen, filter and separate. It is also used as a dispersed cooling material in various high-temperature environments, and has the advantages of high precision, high temperature resistance and corrosion resistance. What is more, it can also be used as a material for gas distribution and fluidized bed orifice. Stainless steel has many advantages, such as a wide range of operating temperatures and high temperature resistance, good secondary processing, welding and assembly performance. Compared with the powder filter, the sintered mesh has a higher filtration accuracy. For example, the micron of powder filter is 0.2-120μm, and the sintered mesh filter can be 1-1000 μm.

Then how to distinguish the material of stainless steel sintered mesh?

For example: The main difference between 201 and 304 is the content of nickel and chromium. Standard 304 stainless steel contains 18% chromium and 9% nickel. 201 stainless steel contains 15% chromium and 5% nickel. The higher the content of nickel and chromium, the better the rust resistance of stainless steel, of course the price will be as well as higher.

In terms of corrosion resistance, 201 contains manganese, which will rust in a humid or high-salt environment for a long time. The corrosion resistance of 304 is much better than that of 201. In addition, the corrosion resistance of 316 stainless steel is greatly improved due to the addition of Mo element. For acid and alkali resistance, 201 has a small content of nickel, so its acid and alkali resistance is weaker than that of 304. The acid and alkali resistance of 304 is weaker than that of 316.

Moreover, the difference in material determines the usages and fields. If it is a coastal, humid, high temperature and other places that are prone to rust, 304 or 316 materials with better corrosion resistance should be the best choice.
