Why need pickling and passivation of stainless steel wire meshWhy 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. Hebei Maishi 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.

Why need pickling and passivation of stainless steel wire meshHebei Maishi 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.

Why need pickling and passivation of stainless steel wire meshStainless 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.

Hebei Maishi wire mesh production of stainless steel wire mesh, surface cleaning, pickling and passivation, in addition to maximize corrosion resistance, as well as to prevent product contamination and get beautiful role.Why need pickling and passivation of stainless steel wire meshIn GBl50 — 1998 << Steel Pressure Vessel >> states that " the surface of the stainless steel container corrosion requirements and composite steel plate should be pickling passivation." This provides a pressure vessel for use in the petrochemical industry is concerned, since these devices are used in direct contact with the corrosive medium case, starting from the securing corrosion resistance corrosion, pickling and passivation is made necessary.

Why need pickling and passivation of stainless steel wire meshFor other industrial sectors, if not for the purpose of corrosion, clean and beautiful only on request, and the use of stainless steel, Hebei Maishi 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.
