Paul;
Plating causes hydrogen embrittlement of high alloy steels. This affects its
strength and particularly its fatigue strength. An alloy steel part can be
baked-out in an oven after plating but the temperature can't be so high that
it ruins the heat-treat temper.
Better than plating is simply painting or low temperature powder coating.
Low alloy steel (mild steel) doesn't have the same hydrogen problems as high
alloy steel. In general, the higher the steel's tensile strenght, the more
you need to avoid electroplating.
One exception to the plating rule is plating with electroless nickel. I
don't think this has the hydrogen problem to the same degree as
electroplating. Double check this, though-- maybe someone else can comment
on electroless nickel.

List, anyone have any info on the effects that chrome plating (and brass)
has
on chrome moly and mildsteel tubing? Does it have any effect on strength
etc....?
Paul, in the UK where the weather is unseasonably pleasant.
