Metal finishing shops with in-house passivation in California

Passivation chemically cleans stainless steel and restores its protective oxide layer so machined parts resist corrosion — done in the shop's own line.

Give the stainless grade and the spec (ASTM A967 or AMS 2700, nitric or citric); ask whether they test after passivation and how parts are packaged to stay clean.
