Stainless steel wire mesh has good corrosion resistance, high-temperature oxidation resistance, low-temperature resistance performance. Therefore, it is widely used in industries such as screening and filtration under acid-base environment.
Its main function is to prevent corrosion and rust. The corrosion resistance of stainless steel wire mesh mainly depends on the passivation film on its surface. If the film is incomplete or defective, the stainless steel will still be corroded. Passivation treatment is generally adopted in engineering to make stainless steel have greater corrosion resistance potential.
Formation and assembly of stainless steel equipment and components, welding, weld seams quality inspection, such as inspection and pressure testing, its surface oil, rust, non-metallic dirt, paint, welding slag, low melting point metal contaminants and splashes
These substances will affect the surface quality of the stainless steel, destroy the oxide film on the surface, reduce the overall corrosion resistance and local corrosion resistance of the stainless steel wire mesh (including pitting corrosion, crevice corrosion), and even cause stress corrosion cracking. Stainless steel wire mesh surface cleaning, pickling and passivation,
in addition to maximizing corrosion resistance, can also prevent product pollution and aesthetic effects. It is the purpose of filtration in the petrochemical industry to require the pickling and passivation treatment of containers made of stainless steel wire mesh and composite steel plates because these devices are directly in contact with corrosive media.
For other industries, if not for the purpose of anti-corrosion, only based on cleaning and aesthetic requirements, and the use of stainless steel materials does not require pickling and passivation. However, the welding lines of stainless steel equipment also need to be pickled and passivated.
Stainless steel wire mesh is made of stainless steel as raw materials to make various types of silk products, and the cross-section is generally round or oblate. Ordinary stainless steel wire mesh has good corrosion resistance and high-cost performance.
