Passivation of stainless steel
Passivation of stainless steel consists of forming a protective oxide layer on the alloy.
The principle of passivation
The passivation process accelerates the natural formation of chromium oxide, ensuring optimal surface protection.
This treatment by immersion in an acid solution allows the formation of a thin layer of chromium oxides. This layer cleans and eliminates oxides and contaminating residues, thus giving the stainless steel its so-called passivation state.
The benefits of passivation
- Corrosion resistance: Forming a protective oxide layer.
- Removal of contaminants: Cleaning of iron oxides and other residues.
- Increased durability: Extends the life of parts.
- Aesthetic improvement: Cleaner and more uniform finish.
- Preservation of mechanical properties: No impact on strength and ductility.
- Compliance with standards: Meeting industrial requirements.
- Reduced maintenance costs: Fewer repair needs.
