EdStainless, We'll use your recommendation above for pickling. I thought we had expertise on campus with this but looks like it will be another science experiment! I did pass a few under a TIG brush that we use to clean welds, and it certainly made the rods look marginally better.

Thank you again for your replies. Once we remove the oxide layer, is the HT foil pouch enough to prevent issues with the N atmosphere or would you recommend we find a shop that can perform the work in a N-free or evacuated environment?
Thanks so much for your reply! The forming is not that aggressive and is in a localized area. Unfortunately we did not check hardness after the 1400F step. As far as the atmosphere . . . um . . . well . . . let's say it's rather nitrogen rich at around 78% . . .
Would that effect properties...
I have inventory of 17-7PH rods, 6mm diameter, in Condition C. I need to perform a forming operation to the rod that is not possible in condition C. Due to supply issues, I was not able to purchase the material annealed, so we used the following recipe to attempt to anneal it, form it, then...
