Re: Stud welding stainless

You need even more caution in a marine envireonment. Stainless
corrodes in stale saltwater. Here in Washington State some of the
state ferries were fitted with stainless steel pipe for the saltwater
fire sprinkler system. The saltwater in the pipes lost its disolved
oxygen which in necessary to keep the surface coated with chrome oxide.
The chlorine corroded the pipes and they all had to be replaced with
regular pipe.

I would think the studs and back side of the plate would be a similar
situation. So mild steel may be better than stainless in this case.
I hope you have smarter engineers than our state ferry engineers.

haven't started studding so hopefully a welding engineer is being consulted.
It also doesn't make sense to have a stainless plate against concrete with
carbon steel anchors in the concrete. This is a marine environment.
