(OP)
There has been a concern raised of "gaulding" of stainless nuts when used with the stainless steel "studs" that we have in place. Is there a good reason to use carbon steel versus stainless in this application. Corrosion at the point of these fasteners is not an issue, the only reason that the studs is stainless is that the hoppers that they are attached too are stainless. Thanks in advance.





RE: stainless fasteners
Don't know, you haven't told us anything about your application.
RE: stainless fasteners
yes when using stainless to stainless fastener connections you must use an anti-sieze agent or you run the risk of the nut and stud Galling together.
There are several good anti-sieze compounds available, from relatively low temp ones to some that are designed to operate up to 1500F. Do a search on Metal and Metallurgy fourm.
I dont know about carbon versus stainless as far as you application cause like MintJulep I dont know your application.

I love materials science!

Use Neverseez to prevent galling of stainless-stainless

NeverSeez will work on heater installations - I usta use it on my muffler U-bolts - the nuts would come off easy, with clean threads underneath, even though everything else was rusty & crusty. The metal flakes stay behind, even if the grease part evaporates.
RE: stainless fasteners
I would suggest that your studs match the hopper material. You can use a 4XX stainless nut and a Cu or Ni containing anti-seeze, you should be fine.
