Pickling and passivation stainless steel
WebbPassivation is a widely used metal finishing process to prevent corrosion in stainless steel, the passivation process uses nitric acid or citric acid to remove free iron from the surface, the chemical treatment leads to a protective oxide layer that is less likely to chemically react with air and cause corrosion, passivated stainless steel resists rust. WebbThe pickling process ( Circulation or immersion with INOX Pickling Liquid ) removes the passive layer and slightly etches the surface of the stainless steel in order to clean the surface propperly. ( Embedded steel, contamination by “fremdkorper”, heat tint ( …
