Recommend coating
(OP)
I will need to coat the inside of a vessel operating under vacuum. The protection required is for HCL (Hydrochloric acid) and temperatures to around 300 F.
Does any body have a recommendation for the coating to use for this application. The vessel surface to be coated is Stainless Steel.
Any help would be greatly appreciated

Why SS? If it ever gotwet then the pitting and stress cracking would be real isses.

PTFE, Polytetrafluoroethylene (aka TeflonTM) seems best. Be sure that it's non-porous, either well-fused or a double layer.
For seals, a perfluoroelastomer (Chemraz® Greene, Tweed & Co.) is recommended. http://ww
As noted above, stainless has little resistance to HCl. Tantalum & zirconium are much, much better.

Very expensive but well worth it over time.
