Post Wash of Nitric solution from passivate

2004

I am currently producing a stainless steel hinge (304 ss) that requires passivate. If the hinge is not taken apart, the (2) leaves and the hinge pin, does the Nitric acid from passivate have any adverse effect to the stainless if not completely washed?

The nitric acid left on the spring will definitely cause problems. You can get pit corrosion upon aging in addition to the hazard of the acid itself when it might touch another surface.
