Functions of stainless steel screen
Stainless steel screen has seven basic functions: 1. Particle screening and sieving; 2. Air filtering; 3. Filtration; 4. Light transmission; 5. Boundary; 7. Conductive.
The purpose of stainless steel screen.
Stainless steel screen sheet
The purpose of stainless steel screen is very wide: primary industry: agriculture, forestry, animal husbandry, fishery (poultry, fresh/seawater aquaculture, fishing; grassland, animal enclosure, etc.); secondary industry: industry (metallurgy, mining, machinery manufacturing, aerospace, etc.), petrochemical (mud net, liquid, gas filtration, purification, etc.) pharmaceutical, ceramics, glass (screening particles, powder, etc.), paper printing (printing plate net), military industry (battery conductive net, etc.); tertiary industry: transportation (highway, railway, airport enclosure), scientific and technological research and development, construction, cultural life (computer, television, radio, air conditioning, refrigerator, mobile phone, telephone); food, clothing, housing and transportation (high-end suits, Simmons mattresses, food processing, grain processing, etc.).
The types of stainless steel commonly used to process stainless steel screens are generally 201, 202, 304, 316, and 202 and 304 are more commonly used.
316 and 317 stainless steel (the performance of 317 stainless steel is shown below) are molybdenum and chromium-containing stainless steels. The molybdenum content in 317 stainless steel is slightly higher than that in 316 stainless steel. Due to the molybdenum in the steel, the overall performance of this steel is better than that of 310 and 304 stainless steel. Under high temperature conditions, when the concentration of sulfuric acid is lower than 15% and higher than 85%, 316 stainless steel has a very wide range of uses. 316 stainless steel also has good resistance to chloride corrosion, so it is usually used in marine or other large water environments. The maximum carbon content of 316L stainless steel is 0.03, which can be used in applications where annealing cannot be performed after welding and maximum corrosion resistance is required. The corrosion resistance of 316L stainless steel is better than that of 304 stainless steel, and it has good corrosion resistance in the production process of pulp and papermaking. Moreover, 316 stainless steel is also resistant to erosion by marine and corrosive industrial atmospheres. 316 stainless steel has good oxidation resistance in intermittent use below 1600 degrees and continuous use below 1700 degrees. It is best not to use 316 stainless steel continuously in the range of 800-1575 degrees, but when 316 stainless steel is used continuously outside this temperature range, the stainless steel has good heat resistance. 316L stainless steel has better resistance to carbide precipitation than 316 stainless steel and can be used in the above temperature range. The stainless steel screen made of it is widely used.
Annealing is carried out in the temperature range of 1850-2050 degrees, followed by rapid annealing and then rapid cooling. 316 stainless steel cannot be overheated for hardening.

316 stainless steel mesh, using the good welding performance of 316 stainless steel. All standard welding methods can be used for welding. When welding, 316Cb, 316L or 309Cb stainless steel filler rods or welding rods can be used for welding according to the purpose. In order to obtain the best corrosion resistance, the welded section of 316 stainless steel needs to be annealed after welding. If 316L stainless steel is used, no post-weld annealing is required. The obtained stainless steel mesh is of high quality and widely used, and has won praise from various stainless steel mesh users.

Stainless steel mesh is made of chromium and nickel added to iron to form chromium-nickel stainless steel. It is a better stainless steel mesh. The wire mesh processed from this material is called "stainless steel mesh". A large amount of nickel is added to this stainless steel to obtain a single austenite structure, thereby improving its corrosion resistance and processability. It has strong plasticity and toughness at room temperature and low temperature, is non-magnetic, and has good resistance to intergranular corrosion.

1. The influence of nickel on stainless steel mesh can only be fully manifested when it is combined with chromium. Nickel is an alloying element that forms austenite. When nickel and chromium are used in a reasonable combination, the metallographic structure can be changed from single-phase ferrite to austenite and ferrite dual-phase structure. After heat treatment and other steps, the strength can be improved, so that it has stronger stainless corrosion resistance and good deformation performance.

2. Chromium plays a major role in the corrosion resistance of stainless steel mesh: Chromium is the main element that determines the corrosion resistance of stainless steel, because the chromium content in steel can make stainless steel passivate in an oxidizing medium, that is, a very thin film is formed on the surface, and chromium is enriched in this film. The higher the chromium content in the steel of the stainless steel mesh, the stronger the corrosion resistance. In addition, chromium can play a good role in strengthening the mechanical properties and process properties of the steel of the stainless steel mesh.

3. The influence of impurities on performance
When the carbon content is between 0.1% and 0.3%, after annealing, carbon will precipitate in the form of graphite on the lattice boundary, destroying the bonding force between grains, strongly reducing the strength and plasticity of nickel, and making processing deformation difficult. In addition, carbon has a strong affinity with chromium and can form a series of carbides. The higher the carbon content in the steel, the more chromium carbides are formed, the chromium content in the solid solution is relatively reduced, and the corrosion resistance of the steel will be reduced. Sulfur is a harmful impurity. Sulfur and nickel form Ni3S2 compounds. Ni3S2 and nickel form a low-melting eutectic at 625℃ and are distributed on the grain boundaries. When the heat deformation temperature exceeds the eutectic melting point, cracks will occur along the grain boundaries, resulting in the so-called "hot brittleness" phenomenon. Ni3S2 generated by nickel and sulfur at room temperature can cause cold brittleness.

Stainless steel wire mesh is heat-resistant, acid-resistant, corrosion-resistant and wear-resistant. These characteristics make stainless steel wire mesh widely used in mining, mining engineering, chemical, biological, food, machinery, medicine and other industries.
