PASSIVATION
Sub Source provides stainless steel passivation services in Rockford, Illinois, as part of our metal preparation and finishing capabilities. Send your material, drawings, and process requirements so our team can review the work before quoting.
What passivation does
Passivation is a chemical treatment used to remove free iron and other surface contamination from stainless steel. It supports the surface condition needed for the material’s natural corrosion resistance. It is not a paint or a protective coating applied over the part.
The treatment and verification requirements depend on the alloy and governing specification. Passivation should not be described as a way to increase impact strength or as a substitute for every cleaning, descaling, or finishing operation.
Specify the required process
Include the stainless steel grade, incoming condition, drawing revision, required specification and revision, treatment requirements, and acceptance criteria. If your drawing calls out ASTM A967/A967M or another standard, provide that requirement for review; do not assume a particular treatment or test is included without confirming the order.
Tell us about machining oils, previous processing, weld discoloration, scale, or other surface conditions. These details help identify whether additional preparation must be considered before passivation.
Coordinate related metal finishing
If your parts also require ultrasonic cleaning, other metal finishing, or nondestructive testing, send the complete process sequence and inspection requirements. Our team can review the requested services together.
