964T #304 You mention you've been around inconel and hastaloy. I have a small repair to do in the next few days where there is a discrepancy surrounding the parent metal being inconel or hastaloyX. (these may be the same for all I know, and care) Regardless, I obtained a repair procedure manual but there is no mention of back purging, likely due to difficulty within the repair environment. I'm curious, do you know if inconel and hastaloyX develop the same rough crystal structure on the backside as non-purged 304/321?
I would suggest the back purge for your repair as well. I have seen sugar on hastaloy and inconel non backed.
