Can S/S B8 studs and S/S SA194 Nuts be used on Carbon steel A105 Flanges ?
I have an application that the external environment is corrosive and from experience the Studs and nuts are always corroded after few months. However the flanges don't corrode because they are painted with special painting resisting to the environment.
So I would like to use S/S studs and nuts on C/S flanges. Anyone has any idea if it can cause any problem ?
Thank you

I don't know of any reason you CAN'T use stainless.

Plus stainless hardware is just a massive pain in general...
What is the external environment that's so corrosive?
I've seen PTFE coated studs, liberally lubricated, used to good effect around cooling towers and the like.

PTFE coated bolts should not be used as a means of corrosion protection. They are merely designed to lower friction.

They have been specified by chemical plants for decades now.... some companies swear by them.
