Do You Know Stainless Steel Mesh?
Stainless steel wire mesh stainless steel has good corrosion resistance, high temperature oxidation resistance, low temperature performance and excellent mechanical performance.Therefore, it is widely used for screening and filtration under the conditions of acid and alkali environment, chemical filler, petroleum sieve net and other industries.Its main purpose is to prevent corrosion and rust.The corrosion resistance of stainless steel wire mesh mainly depends on the passivating film on the surface. If the film is incomplete or defective, the stainless steel will still be corroded.Engineering is usually performed on the passivation treatment, so that the corrosion resistance potential of stainless steel is greater.In a stainless steel equipment and parts in the forming and assembling, welding, weld inspection, such as inspection, pressure test in the process of its construction and tag with surface oil, rust, non-metallic dirt, paint, welding slag, low melting point metal contaminants and splash content etc, these substances affect the surface quality of stainless steel equipment and parts, destroyed the surface oxidation film, reduces the overall corrosion resistance of stainless steel mesh performance and local corrosion resistance (including pitting, crevice corrosion), even lead to stress corrosion cracking.Stainless steel screen surface cleaning, pickling and passivation, in addition to the maximum enhancement of corrosion resistance, but also to prevent product contamination and aesthetic effect.The requirement that containers made of stainless steel wire mesh and composite steel plate should be subjected to acid cleaning passivation is for the purpose of filtration used in petrochemical industry, because these devices are used for direct contact with corrosive medium.For other industries, if not for the purpose of antisepsis, only based on the cleaning and aesthetic requirements, while the use of stainless steel materials do not require pickling passivation.However, the welding line of stainless steel equipment still needs to be processed by pickling and passivation.
Stainless steel wire, also known as stainless steel wire, stainless steel for raw materials to make a variety of different specifications and models of silk products, the section is generally circular or flat.Common stainless steel wire with good corrosion resistance and high cost performance is 304 and 316 stainless steel wire.Stainless steel wire drawing. Under the action of drawing force, wire rod or wire blank is pulled out of the die hole of wire die to produce small section steel wire or nonferrous metal wire metal plastic processing.Various metals and alloys of different section shape and size of the metal silk can be produced by drawing.Drawn out of the silk, accurate size, smooth surface, and the use of drawing equipment and mold simple, easy to manufacture.
