  • What is Passivation? How Does Stainless Passivation Work?

    The stainless steel passivation process chemically removes these free irons and forms a passive oxide “film” layer which further improves corrosion resistance. When exposed to air (oxygen), the stainless steel undergoing passivation will form a chemically inactive or inert chromium oxide surface.
