Manufacturing Process
Passivation
Chemical surface treatment used to help stainless steel form and maintain a clean passive layer after machining or fabrication.
Process Overview
Passivation for industrial component production
Chemical surface treatment used to help stainless steel form and maintain a clean passive layer after machining or fabrication.
Process selection should be confirmed by material, geometry, tolerance, surface finish, quantity, application environment and inspection requirement.
Engineering Data
Materials, advantages, limitations and applications
Typical Materials

FAQ
Process selection questions
Can AODSON recommend a process from drawings?
Yes. Send drawings, samples, material, quantity and application details for RFQ review.
Is the same process suitable for every material?
No. Material grade, geometry, tolerance and surface finish determine the suitable process route.
Can casting and machining be combined?
Yes. Many complex parts use casting for shape and machining for critical dimensions.
