Unlike chemical passivation, acid pickling will etch the surface of the stainless steel, removing material.
Pickling 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.Stainless Steel Finishing ChemicalsAvesta BlueOne Pickling Paste 130 is universally, suitable for brush pickling of welds and smaller surfaces on all stainless steel grades.
