Frequently Asked Questions

What is passivation and how does it work?

Passivation is a chemical process that removes free iron and contaminants from stainless steel surfaces. Parts are immersed in a solution that enhances corrosion resistance without changing the part’s appearance or dimensions.

What are the benefits of passivation for stainless steel parts?

Passivation improves corrosion resistance, removes contaminants, and enhances surface cleanliness. It is widely used in aerospace, medical, and industrial applications where rust prevention is critical.

What specifications does Rayco meet for passivation?

Rayco Metal Finishing performs passivation in accordance with AMS 2700, ASTM A967, and other industry standards to meet strict compliance requirements.

What types of parts are best suited for passivation?

Passivation is ideal for stainless steel components that require corrosion resistance and clean surfaces, including medical devices, aerospace parts, firearms components, and precision-machined parts.

How do I know if passivation is the right process for my project?

If your goal is to improve corrosion resistance without changing the appearance or dimensions of stainless steel parts, passivation is often the best solution. Rayco can help determine the appropriate specification for your application.
