Stainless Steel Passivation Services
Tecomet Inc. is a chemical machining & etching company that offers stainless steel passivation services. Our team has 30 years of experience, and can provide passivation services for a wide range of industries.
What Are Etched Metal Passivation Services?
Passivation is a chemical treatment that removes particles and contamination left behind in the fabrication process.
Why Are Etched Metal Passivation Services Necessary?
New stainless steel parts must be passivated prior to being placed in services so that your part is capable of forming a passive film on the cleaned surface, which will prevent corrosion and rust. Stainless Steel Passivation not only helps your industrial part achieve optimal performance but also extends the time between scheduled maintenances.
Applications of Metal Passivation Etched Parts
Industries that benefit from etched metal passivation services:
- Medical & Surgical– passivation for medical devices cleans medical implants so that they are safe and free of metal oxides before use
- Biopharmaceutical – passivation can remove residue to sanitize drug production equipment
Electropolishing vs. Passivation
While both passivation and electropolishing services clean and protect metal alloy tools and equipment, passivation is a less aggressive method that should be used when aesthetics are not necessary for a part. These services can also be used together to achieve a superior finish.

FAQs
What happens if a new stainless steel part is put into service without being passivated first?
The part won’t have formed the protective passive film that shields the surface from corrosion and rust, leaving it vulnerable to premature degradation. This is why passivation is treated as a required pre-service step for new stainless steel etching parts, not an optional finishing touch.
Why does passivation extend the time between scheduled equipment maintenance?
By forming a stable, corrosion-resistant film on the surface, passivation slows the rate at which stainless steel degrades or rusts over time. That slower degradation means parts need less frequent inspection, cleaning, or replacement — directly reducing long-term maintenance costs and downtime.
Is passivation alone sufficient for biopharmaceutical equipment, or is additional finishing typically needed?
Passivation removes residue and helps sanitize contact surfaces, but Tecomet notes it can be combined with electropolishing to achieve a superior finish — relevant when biopharmaceutical equipment needs both contamination control and a smoother, easier-to-clean surface rather than corrosion resistance alone.
