What type of material should stainless steel wire mesh be used in the industry?

 Considering the differences in corrosion resistance, toughness, strength and weldability of stainless steel materials in practical applications in various industries, when choosing stainless steel wire mesh, the main consideration should be what material to choose.
　 1. Ferritic stainless steel: containing 12% to 30% chromium. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and its resistance to chloride stress corrosion is better than other types of stainless steel. This category includes Crl7, Cr17Mo2Ti, Cr25, Cr25Mo3Ti, Cr28, etc. Ferritic stainless steel has good corrosion resistance and oxidation resistance due to its high chromium content, but poor mechanical and process properties. It is mostly used for acid-resistant structures with little force and as oxidation-resistant steel. This type of steel can resist corrosion from the atmosphere, nitric acid and brine solutions, and has the characteristics of good high-temperature oxidation resistance and small thermal expansion coefficient. It is used in nitric acid and food factory equipment, and can also be used to make parts that work at high temperatures, such as gas turbine parts. 　　
　 2. Austenitic stainless steel: contains more than 18% chromium, about 8% nickel and a small amount of molybdenum, titanium, nitrogen and other elements. It has good comprehensive performance and can resist corrosion from a variety of media. Common grades of austenitic stainless steel include 1Cr18Ni9, 0Cr19Ni9, etc. The wC of 0Cr19Ni9 steel is less than 0.08%, and the steel number is marked as "0". This type of steel contains a large amount of Ni and Cr, which makes the steel austenitic at room temperature. This type of steel has good plasticity, toughness, weldability and corrosion resistance, and has good corrosion resistance in oxidizing and reducing media. It is used to make acid-resistant equipment, such as corrosion-resistant containers and equipment linings, pipelines, and nitric acid-resistant equipment parts. Austenitic stainless steel generally adopts solid solution treatment, that is, the steel is heated to 1050-1150℃ and then water-cooled to obtain a single-phase austenitic structure. 　　
　 3. Austenite-ferrite duplex stainless steel: It has the advantages of both austenite and ferrite stainless steels and has superplasticity. Austenite and ferrite structures each account for about half of the stainless steel. In the case of low C content, the Cr content is 18%~28%, and the Ni content is 3%~10%. Some steels also contain alloying elements such as Mo, Cu, Si, Nb, Ti, and N. This type of steel has the characteristics of both austenite and ferrite stainless steels. Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, and significantly improved intergranular corrosion resistance and welding performance. At the same time, it also maintains the 475℃ brittleness and high thermal conductivity of ferrite stainless steel, and has the characteristics of superplasticity. Compared with austenitic stainless steel, it has high strength and significantly improved resistance to intergranular corrosion and chloride stress corrosion. Duplex stainless steel has excellent pitting resistance and is also a nickel-saving stainless steel. 　　
　 4. Martensitic stainless steel: high strength, but poor plasticity and weldability. Common grades of martensitic stainless steel include 1Cr13, 3Cr13, etc. Due to the high carbon content, they have high strength, hardness and wear resistance, but slightly poor corrosion resistance. They are used for parts with high mechanical properties and general corrosion resistance requirements, such as springs, turbine blades, hydraulic press valves, etc. This type of steel is used after quenching and tempering.
