What Is The Difference Between Pickling & Passivation

Passivation uses either nitric acid or citric acid that are not recognized as being as aggressive as the acids used in pickling. Passivation does not typically go below the surface of the metal and does not change the properties of the metal. The oxide layer left by passivation is only .0000001 inch thick.What Is The Difference Between Pickling & PassivationPassivation uses either nitric acid or citric acid that are not recognized as being as aggressive as the acids used in pickling.

Why Stainless Steel Pipe Needed Acid Pickling And Passivation?

Actually,pickling and passivation refers metal submerged in a bathing liquid that removes imperfections and rust from the surface of stainless steel. Where the steel has been heated by welding, or other heat treatments,to the point where a coloured oxide layer can be seen, there is a chromium depleted layer on the surface of the steel underneath the oxide layer.Why Stainless Steel Pipe Needed Acid Pickling And Actually,pickling and passivation refers metal submerged in a bathing liquid that removes imperfections and rust from the surface of stainless steel.
