Passivation for Stainless Parts
Restore corrosion resistance after machining stainless — typical for SS304 / SS316 export jobs.
When buyers ask for it
SS304 / SS316 export jobs often add passivation after machining to restore the chromium oxide film. Select Passivate on the quote finish list; it adds finish days on the production clock.
Not a plated coating
Passivation is a chemical clean / oxide restore, not nickel or zinc plating. Plating, if needed, is reviewed case by case — we do not list fake in-house plating lines.
