Why need pickling and passivation of stainless steel wire mesh

 Corrosion resistance of stainless steel wire mesh, rely mainly on the surface passivation membrane, if the film is incomplete or flawed, stainless steel wire mesh will corrode. Anping Huaxi wire mesh production of stainless steel wire mesh, pickling passivation processing normally on engineering, make the corrosion potential of stainless steel wire mesh to the larger.

Anping Huaxi wire mesh production of stainless steel wire mesh, with good corrosion resistance, high temperature oxidation resistance, good low temperature performance, excellent mechanical. Therefore, Hebei Maishi wire mesh production of stainless steel wire mesh, widely used in chemical, petroleum, power, nuclear engineering, aerospace, marine, medicine, light industry, textile and other sectors. The main purpose of corrosion and rust.

Stainless steel equipment and components to bring the surface oil, rust, dirt nonmetallic, low melting point metal contaminants, paints, welding forming, assembly, welding, weld inspection ( eg inspection, pressure test ) and in the course of construction markings slag and spatter, these substances affect the surface quality of the stainless steel equipment and components, destruction of the oxide film on the surface, reducing the overall corrosion resistance of steel, and resistance to localized corrosion ( including pitting, crevice corrosion ), and even lead to stress corrosion cracking.

For other industrial sectors, if not for the purpose of corrosion, clean and beautiful only on request, and the use of stainless steel, Anping Huaxi  wire mesh suggest you, don't need pickling passivation. But the weld stainless steel equipment, but also the need for pickling passivation. Nuclear engineering, some chemical plant, and other stringent requirements, in addition to pickling passivation, but also the use of high purity media for final fine cleaning or mechanical, chemical and electrolytic polishing finishing treatment.
