Pickling and Passivation

Pickling and Passivation. Stainless steel can corrode in service if there is contamination of the surface. Both pickling and passivation are chemical treatments applied to the surface of stainless steel to remove contaminants and assist the formation of a continuous chromium-oxide, passive film. Pickling and passivation are both acid treatments and neither will remove grease or oil. Pickling and passivation of stainless steel systems Although the stainless steel will spontaneously passivate after pickling (forming a protective chromium oxide film) by exposure to sufficient oxygen in the outside air, closed systems are generally chemically passivated. The passivation fluid is circulated through the

The necessity of stainless steel pickling passivation

The principle of stainless steel pickling passivation The corrosion resistance of stainless steel is mainly due to the surface is covered with a very thin (about 1nm) dense passivation film, which is isolated by 1nm corrosive medium and is the basic barrier for stainless steel protection. Thin walled stainless steel tubing with high strength and After the reaction of the chemical agent, a passivation effect is formed, and a layer of stainless steel pipe is formed on the surface, and if the pipe member is subjected to de-doping, pickling, and passivation treatment, the thickness of the generated Cr2O3 can be increased, and the uniformity of compactness is enhanced, and the stainless
