All stainless steels are ferrous and I would think that they'd thus all be
subject to RF heating.
The 300 series alloys have, in general, a higher percentage of chromium and
nickel and are not magnetic. Some of the 400 series alloys have nearly as much
but are magnetic. In either case, the Fe content is still around 70% or more.

I just checked with one of the fellows who has designed his
share of high-power HF rigs and he says brass is the way
to go. It is usually cadmium-plated to "keep it shiny looking."
Apparently there are varying grades of "stainless" steel and
some of them are truly bad in RF. High grade SS is OK but
since you can' tell easily the rule was to simply avoid it.
This note concerns the nuts and bolts used to hold the
assembly together.
