Passivation: Gives stainless steel surfaces a protective surface to resist corrosion. Wonder Gel is a superior pickling gel that thoroughly removes rust, oxides, scale and other impurities from stainless steel surfaces. A carefully balanced formulation of effective pickling agents combined with special inhibitors, Wonder Gel removes impurities passivation and pickling listWhat Is The Difference Between Pickling & PassivationWhat Is The Difference Between Pickling & Passivation. On the surface there does not seem to be a big difference between the two processes. The differences come down to the intensity of the treatments. Pickling uses acids that take off the surface of the metal to treat impurities as a sublevel basis. Pickling leaves a greater change to the metal. Passivation uses either nitric acid or citric acid that are not Using Pickling and Passivation Chemical Treatments to passivation and pickling listDec 05, 2017 · 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.

The chemical solutions in pickling are much aggressive than the acids used in passivation of stainless steel. In pickling, it uses the mixtures of hydrofluoric and nitric acids. The process of Pickling leaves greater changes on the metal surface.
Best: Spray Pickling & Passivation. Spray pickling is the most common chemical process to remove oxides and iron contamination.

Both pickling and passivation are chemical processes that are utilized to provide protection to metals against corrosion and pitting. In either process, an acidic solution is applied to the metal surface to remove contaminants and to aid in the formation of a continuous, chromium-oxide passive film. Without pickling and/or passivation, stainless steel is subject to corrosion in service which can lead to costly quality issues.See more on astropak passivation and pickling listPhoenix AZ Passivation, Electropolishing & Plating CompanyNote: Our passivation and electropolishing facility is centrally located in Kansas due to the ease of delivering and receiving pieces and parts from all over the country.

Pickling is the removal of any high temperature scale and the low chromium layer of the steel surface by a chemical treatment such as nitric or hydrofluoric acids. Because pickling involves a removal of metal layers, it can sometimes cause a change in appearance. Passivation and PicklingPassivation and Pickling - Valve MagazineNitric acid and citric acid-based solutions are the most commonly used chemicals for passivation. Many vendors add their own blend of proprietary chemicals and additives to enhance the effectiveness of these acid-based solutions. Pickling, often referred to as chemical descaling, is a more aggressive chemical treatment than passivation.
