stainless steel sheet coil reduces the overall

Stainless steel reduces the overall corrosion resistance and resistance to localized corrosion ( including pitting , crevice corrosion ) , and qiyi 304 stainless steel coil to stress corrosion cracking . Stainless steel mesh surface cleaning , pickling and passivation , except to maximize corrosion resistance , as well as to prevent product contamination and get beautiful role . Stainless steel mesh surface of the container made ​​of composite steel and has a corrosion requirements of this provision shall be pickling passivation is used for filtration in terms of petrochemical , because these devices for direct contact with the corrosive medium occasions corrosion corrosion resistance from the guarantee , raised pickling passivation is necessary. To other industries, such as the purpose is not for corrosion , clean and beautiful only 430 stainless steel magnetic, and you do not need the use of stainless steel pickling passivation . But also need to weld stainless steel equipment pickling passivation , the passive film on stainless steel mesh repair improved anti-corrosion properties .
