Austenitic stainless steel wire mesh boasts exceptional corrosion resistance, high temperature oxidation resistance, and excellent mechanical properties. It finds extensive applications in various sectors, including chemical, petroleum, power, aerospace, marine, and more. The primary purpose of stainless steel wire mesh is to prevent corrosion and rust, ensuring long-lasting durability.
The corrosion resistance of stainless steel largely depends on the surface passivation film. If this film is incomplete or defective, the stainless steel is prone to corrosion. This is where pickling passivation treatment comes into play.
During the formation, assembly, and welding processes of stainless steel equipment and components, contaminants like surface oil, rust, non-metallic dirt, and low melting point metal impurities can affect the surface quality. These contaminants can damage the oxide film, compromising the overall corrosion resistance and leading to localized corrosion and stress corrosion cracking.
Surface cleaning, pickling, and passivation of stainless steel wire mesh not only enhance corrosion resistance but also prevent product contamination and improve aesthetics. In industries such as petrochemicals, pickling and passivation are mandated for pressure vessels that directly come into contact with corrosive media. Other industrial sectors may require pickling passivation based on corrosion protection needs, cleaning requirements, or aesthetic considerations.
