Zinc plated hardware against stainless steel

[nwitt]

Are there any concerns with using zinc plated hardware against 316 L stainless steel? The application is a steam ejector.

I'm not a metallurgy person so please advise if you need additional information to be able to answer the question.

The zinc will be preferentially corroded, probably very quickly. It is best to use stainless steel hardware in contact with stainless steel components.
