Hi Guy! You will want to look at the OR and IN flux classifications for
soldering stainless steel as you will need a highly aggressive flux
material to accomplish the task. I have received good counseling from the
folks at Indium and Superior Flux on a couple of applications where I
needed that kind of flux power. Many of the IN fluxes " can solder
concrete" so keep a focus on your cleaning process after soldering. Good
Luck.
