Stainless steels passivation

Passivation is the use of an oxide film on metals and alloys to slow corrosion.
Passivation is a chemical treatment that recreates the surface layer of chromium oxide on stainless steels after this protective layer has been impaired during scouring and formatting operations.
Depending on the configuration of the pieces to be treated, passivation is performed either by immersion in treatment baths or by spraying.
At industrial sites, passivation is performed by by circulation inside networks, by sprinkling, spraying, or runoff, depending on the capacities.
