Other reasons can be that the environmental conditions are not "agressiv" enough to form a passivation layer.

RE: Passivation of Stainless Steel
So my question is, "Do I need to passivate myparts?"
(I am trying to justify not passivating)(It could save a lot of process time / money)

Do you use the exact same carbide tool or T-15/TiN coated tool to machine plain carbon steels? Does the stainless steel come into contact with any fixtures, tubs, conveyors, etc. that are used to process plain carbon steels? If the answer to these questions is yes, then the parts need to be passivated.

Take a sample part and soak it in a 5% NaCl salt bath for 48 hours (if you don't have a dip tester or salt spray capabilities) and see what comes of it. That might be a quick way to see if you have a potential problem.
