I have limited personal experience in this area and manufacturers stick by their product so its hard to get a straight answer...

The use of stainless is not indicated unless it can remain passive in the given environment. The exception is when pitting and perforation are unimportant to the desgn and function, which is not the case with boilers.

Some manufacturers of condensing furnaces use 29-4C SS in the condensing portion of their heat exchangers in NG furnaces. There is little if any welding in these though.
In one application where the flue gas was being exhausted through a water bath, the project was scrapped because the corrosion issues were so bad. The material used was 316L.
