contactStainless steels rely on a very thin surface passive film for their corrosion resistance. It is vital to maintain and preserve the integrity of the passive film. When a Stainless is welded this passive film is damaged and the affected areas require repair by pickling & passivation which is achieved via a dip system.
contactPickling uses more aggressive acids than passivation. The chemicals used for the Pickling of stainless steel can dissolving oxidation, weld oxides and scale and can etch the base material. This process works best for materials that are welded, cast, heat-treated or have existing oxides. Meanwhile, passivation is a separate process to pickling.
