Service Guide
What is stainless steel passivation?
Stainless steel passivation is a chemical treatment that removes free iron contamination and helps restore the natural corrosion-resistant condition of stainless surfaces after machining or fabrication.
Contamination Removal
Removes free iron that can trigger localized rust staining.
Corrosion Recovery
Supports restoration of stainless corrosion-resistant behavior.
Process Reliability
Useful for precision parts with strict cleanliness requirements.
When to Specify Passivation
Specify passivation where stainless parts undergo machining, handling, or fabrication stages that may introduce surface contamination and reduce corrosion reliability.
Include substrate grade, cleanliness expectations, and service environment in your RFQ for better process matching.
