Protect Stainless Steel from Corrosion
Passivation is a chemical treatment process that removes free iron and surface contaminants from stainless steel, helping restore its natural protective oxide layer. The result is improved corrosion resistance, a cleaner surface, and better long-term performance in demanding environments.
At ABS, we provide passivation services for manufacturers who require clean, corrosion-resistant stainless steel components that meet industry specifications. Whether you’re processing medical, aerospace, industrial, or commercial parts, our team delivers reliable results with the quality and turnaround you expect.
Why Choose Passivation?
Although stainless steel naturally resists corrosion, machining, welding, and handling can leave behind contaminants that reduce its effectiveness. Passivation removes these impurities and enhances the material’s ability to resist rust and corrosion without changing its dimensions or mechanical properties.
Benefits include:
- Improved corrosion resistance
- Removes free iron and surface contamination
- Restores the protective oxide layer
- No change to part dimensions or tolerances
- Clean, uniform surface finish
- Helps meet industry and customer specifications
Materials We Commonly Process
ABS performs passivation on a wide range of stainless steel materials, including:
- 300 Series stainless steels
- 400 Series stainless steels
- Precipitation hardening stainless steels
- Martensitic stainless steels
- Austenitic stainless steels
- Many other corrosion-resistant stainless steel alloys
Not sure if your material requires passivation? Our team can review your specifications and recommend the appropriate process.

Frequently Asked Questions
WHAT IS PASSIVATION?
Passivation is a chemical treatment process that removes free iron and other contaminants from the surface of stainless steel. This allows the metal to form a strong protective oxide layer that improves its natural resistance to corrosion.
Why is passivation important?
Machining, welding, and fabrication can introduce contaminants that reduce the corrosion resistance of stainless steel. Passivation removes these contaminants, helping components perform better and last longer in demanding environments.
Does passivation change the size or appearance of my parts?
No. Passivation is a non-dimensional process that does not significantly change the size, shape, or mechanical properties of your components. It simply cleans the surface and enhances corrosion resistance.
What materials can be passivated?
ABS performs passivation on many grades of stainless steel, including austenitic, martensitic, ferritic, and precipitation hardening stainless steels. If you’re unsure whether your material should be passivated, our team can review your specifications.
What is your typical turnaround time?
Most passivation projects are completed within 5 to 7 business days, depending on part quantity and processing requirements. Rush service is available for projects with critical deadlines.
