It is the intensity of the treatments that make a big difference passivation and picklingWhat is Passivation? How Does Stainless Passivation Work?Passivation is a chemical treatment and not an electrolytic process. Passivation does not depend on electrochemical reactions, unlike electropolishing or anodizing. Not for scale removal. Passivating is not a method to remove oxide scale from machined parts after heat treating or welding. Not a coat of paint.

Your Guide to Stainless Steel Passivation

Apr 16, 2020Pickling is very similar to the basic passivation process in that a bath of acidic chemicals is used to strip the surface of the steel. However, where the basic passivation process uses mild nitric acid, pickling uses a more intensive chemical mixture, such as hydrofluoric acid.passivation and picklingpickling and passivation servicesdifference between pickling and passivationpickling and passivation procedurepickling and passivation of pipepickled and passivated stainless steelpickling and passivation pastepickle and passivate companiespassivation vs picklingSome results are removed in response to a notice of local law requirement.
