  1. Pickling and passivation of stainless steel systems and pickling surface stainless steel pipe applied to industry

    The pickling treatment results in a chrome-rich surface. 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.

  2. New Steel Pickling Process Applied Without Nitric Acid

    New Steel Pickling Process Applied Without Nitric Acid The usual challenge for stainless steel pickling involves removing all scale, iron contamination, and welding oxides to achieve a fully passivated surface with an even, clean, and aesthetic finish.

  4. Corrosionpedia - Using Pickling and Passivation Chemical pickling surface stainless steel pipe applied to industry

    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. Surfaces must be free of grease and dirt before using these acid treatments. Stainless steels resist corrosion best if they are clean and smooth.

  9. What Is The Difference Between Pickling & Passivation

    Passivation uses either nitric acid or citric acid that are not recognized as being as aggressive as the acids used in pickling. Passivation does not typically go below the surface of the metal and does not change the properties of the metal. The oxide layer left by passivation is only .0000001 inch thick.

  10. Pickling (metal) - Wikipedia

    Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, rust or scale from ferrous metals, copper, precious metals and aluminum alloys. A solution called pickle liquor, which usually contains acid, is used to remove the surface impurities. It is commonly used to descale or clean steel in various steelmaking processes.
