What Are the Main Types of Materials Used for Stainless Steel Wire Mesh

Sep. 15, 2020

1. Ferritic stainless steel: 12%-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. Crl7, Cr17Mo2Ti, Cr25, Cr25Mo3Ti, Cr28, etc. belong to this category. Because of its high chromium content, ferritic stainless steel has better corrosion resistance and oxidation resistance, but its mechanical properties and process properties are poor. It is mostly used for acid-resistant structures with little stress and as anti-oxidation steel. This type of steel can resist corrosion from the atmosphere, nitric acid, and salt solutions, and has the characteristics of good high-temperature oxidation resistance and low 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, etc. Our company provides iron wire mesh.

2. Austenitic stainless steel: contains more than 18% chromium, and also contains about 8% nickel and a small amount of molybdenum, titanium, nitrogen, and other elements. Good overall performance, resistant to corrosion by various media. Commonly used grades of austenitic stainless steel are 1Cr18Ni9, 0Cr19Ni9, and so on. 0Cr19Ni9 steel has wC<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. It 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 equipment parts, etc. Austenitic stainless steel generally adopts solution treatment, that is, the steel is heated to 1050~1150°C, and then water-cooled to obtain a single-phase austenite structure.

3. Austenitic-ferritic duplex stainless steel: It combines the advantages of austenitic and ferritic stainless steel, and has superplasticity. Austenitic and ferrite structure each account for about half of stainless steel. In the case of low C content, the Cr content is 18% to 28%, and the Ni content is 3% to 10%. Some steels also contain Mo, Cu, Si, Nb, Ti, N, and other alloying elements. This type of steel has the characteristics of austenitic and ferritic stainless steel. Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, and significantly improved intergranular corrosion resistance and welding performance, while still maintaining iron The 475℃ brittleness, high thermal conductivity, and superplasticity of element stainless steel. 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 corrosion resistance and is also nickel-saving stainless steel.  

4. Martensitic stainless steel: high strength, but poor plasticity and weldability. The commonly used grades of martensitic stainless steel are 1Cr13, 3Cr13, etc., because of the higher carbon content, it has higher strength, hardness, and wears resistance, but the corrosion resistance is slightly worse. It is used for higher mechanical properties and corrosion resistance. Some general parts are required, such as springs, steam turbine blades, hydraulic valves, etc. This type of steel is used after quenching and tempering.
