It is impossible to selectively anneal tubing of that size. The best bet to bend it in T0 (dead soft annealed), then if mechanical properties are needed above that, solution heat treat and age for T6.
How would I do this? Make a round bending jig from 1" MDF, using a router bit and pivot arm to precisely route a semicircular channel all around. Route two flat pieces of MDF with channel to grip, then attach both to the bench and go to town. It is best to pivot the jig and fix the flats to the bench, using a lever to pivot the jig
I had to bend several coils from 0.035" wall, 1/4" stainless tube and built a jig like this. Only used a drill press to spin the coils. Nice and tight.
