Passivation of Stainless Steel components conforming to relevant international standards is a crucial post-fabrication chemical treatment that enhances the natural corrosion resistance of stainless steel, and while stainless steel is inherently corrosion-resistant due to its chromium content forming a passive chromium oxide layer when exposed to oxygen, manufacturing processes can compromise this protective layer.
Passivation significantly improves the stainless steel's ability to resist rust and corrosion by removing surface contaminants.
The process chemically removes "free iron" particles and other foreign matter embedded in the surface from machining or fabrication.
It promotes the spontaneous formation of a thin, stable, and non-reactive chromium oxide layer, which is the key to the steel's corrosion resistance.
As a chemical process, passivation does not alter the dimensions, tolerances, or surface finish of the stainless steel part.
The process is purely chemical and does not change the visual appearance or color of the stainless steel.
