I hot salt blued entire guns in a stainless tank from in the mid 1960's until up into the late 1980's & never had any problems with the tank. I had just started my machinist apprenticeship & took over the bluing operation of a machinist in the shop who did gunsmithing on the side. He had the tank made & had used it successfully for some time before I started using it.

Mark,
The former local gunsmith (and a friend), who spend many years at the Army Advanced Marksmanship Unit,building rifles for world class shooters, then spent many more years in his own shop cautioned me against this.He had experience with "spotting" when he tried it. I don't know if this was in one of the several Army shops he worled in, or his own shop. I also don't know whether the tanks were made of 200, 300, or 400 series stainless steel. I considered his advice as authoritative and accepted is experience as true.
Mike

For what it's worth, I hot blued guns for many years, and used some nice stainless baskets for holding small parts. Occasionally there would be one or two parts in the basket that came out white, no blue at all. I would take them out , swish in Brownells rust remover diluted, back in and they would blue fine. After switching to black iron screen baskets, the problem went away. I was using Brownell's salts.
It is not a very scientific test, but the results seem to indicate something.
Lets hear other reports.

I use stainless tanks for all my cleaning and boiling when rust blacking but have a mild steel tank for caustic after getting some coloured sheen on a couple of parts which I'm told was down to a galvanitic reaction. It was greeny blue or dark red tint which showed in certain light . Quiet odd really, I don't understand how it happened but the plain steel tank cured it . I had my tanks made in a local fabrication shop, works out pretty cheap, plus you can decide on the depth and width.
Rust never sleeps !
