  • Passivation of Stainless Steel in Pharmaceuticals | .

    2016-7-13 · Passivation Basics: The term Passivation originates from the word "Passive". Passivation is a natural phenomenon in which an inert layer is formed on the surface of stainless steel alloy, when it is exposed to air or oxidizing atmosphere. Passivation can also be achieved using chemical agents which are basically acid solutions.
