Home Pharmaceutical Passivation Inox Passivation

The presence of exogenous surface contamination, including dirt, grease, free iron from contact with steel tooling, and so forth, may interfere with the formation of the passive film. The cleaning of these contaminants from the stainless steel surface will facilitate the spontaneous passivation by allowing the oxygen uniform access to the surface.

Food/Pharma Pharmaceutical Steel Cleaning Inox Passivation

A food-grade fluorescent reagent is applied to the vessel surfaces and a standard cleaning cycle is carried out, using just water. The vessel surfaces are then inspected using a U.V. light (at a specific wavelength). If full coverage has been achieved, there should be no fluorescence during the inspection.

What is the Passivation Process? Astro Pak

As defined in MIL-STD-753C, the passivation process is the final treatment/cleaning process used to remove iron from the surface of corrosion resistant steel parts such that a more uniform formation of a passive surface is obtained thus enhancing corrosion resistance.
