I do have stainless tape, the kind used for sealing ducting, that's pretty high quality 3M stuff; is that a suitable substitute, or will the adhesive mess with the hardening process in some unknown, strange way? I'm thinking it'll work just as well, as long as the edges are folded properly, as it'll just burn off if it's adhesive out, not touching the part, but I just don't know.
I am imagining that you are relying on the nickle/iron alloy of the stainless steel to over-lay an hardening surface to your tools. Normally impurities in the heating source will alter the final composition of the face hardening alloy deposition. Using oxy. gas as a heat source requires a neutral flame so an indication of the type of forge to be used, viz coal, charcoal, natural gas/air or electric arc is important as is the aging process of the forge construction, excess moisture will alter the hydrgen/oxygen calorific value of the fuel stream.
At best I would use an adhesive solvent to cleanse impurities, and try to ascertain the type of S.S.being used.
