Passivation & Quality Inspection
Passivation
Passivation is a critical finishing step for stainless steel components. The process removes contaminants and enhances the metal’s natural oxide layer—leaving parts clean, consistent, and built for long-term reliability.
- Improves corrosion resistance
- Extends part lifespan and performance
- Ensures compliance with aerospace and other precision industry standards
- Provides a cleaner, more reliable finish
Certified Quality System
Our AS9100-certified process provides full traceability, process control, and accountability.
Advanced Metrology
Parts are inspected with CMMs, height gages, optical comparators, and concentricity indicators.
Extreme Precision
We verify dimensions with micrometer-level accuracy to ensure absolute precision.
Equipment List
