What is Passivation for Stainless Steel Welds? - TIG Brush
Nov 08, 2020 · After welders weld on stainless steel, youll notice that they often clean the welds with a variety of different chemicals, including nitric acid and pickling paste which contains hydrofluoric acid. This cleaning process, also known as passivation, isnt just to enhance the looks of the welds but also prevents corrosion. In other words, passivation is the process of restoring the damaged oxide layer to prevent corrosion in stainless steel.Estimated Reading Time: 5 minsWhat Is The Difference Between Pickling & PassivationNov 12, 2014 · 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.WO1995035397A1 - Process for stainless steel pickling stainless steel slow reaction pickling and passivation gel WeldingThis invention is related to a process for pickling metals, especially rust resistant steel materials, preferably for removing mill scale and other oxide layers, which is characterized in that the metal is brought into contact with a pickling agent comprising, in aqueous solution, in per cent by weight: H2SO4 5-35, H3PO4 5-35, fluoride ion (HF) at least 0.1, Fe3+ at least 0.4, optionally other stainless steel slow reaction pickling and passivation gel Welding
