Stress Releive 12L14 Material during manufacturing
(OP)
I have an application that I have a 4" Dia. Bar x 14" long that I first have a hole drilled thru to remove material. I then send it to Stress Relieve to remove residual
stresses in the Material. Will Stress Relieving help reduce the movement in this part during machining. I believe it will, but would like opinions for others.

If you are further annealing it as a precaution, it may just be moving because of the stress of machining.
Try to evaluate your actual machining stresses, and also try to measure the yield point of your stress relieved blank.
It's just possible that you're doing more harm than good with the stress relief, and you might be better off to eliminate that step and do the rough bore a little less aggressively than I'm assuming you are doing now.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.
