Passivation And Polishing Grade 316 Stainless Steel Casting

  • Passivation and Pickling of Stainless Steel | Stainless

    Passivation is a chemical treatment to the surface of stainless steel that removes contaminants such as free iron and helps form an oxide layer that protects the steel from corrosion. This can be done with either a nitric or a citric acid solution and it generally will not result in a marked change in appearance of the stainless steel surface.
