Self cleaning temp usually in the 700F range.

I have a cast brass foot from an incense boat, (not that it matters, but if
you know what that is, it might give you a better idea of what it looks
like), about 2 inches in diameter. It has been dropped numerous times and
needs to be straightened. I'm thinking of turning a hardwood female mold as
close to the shape as possible, then tapping the rim from the inside out
against the mold until the rim is round and true again. BUT I am worried
about cracking as I straighten it, as a result of work hardening due to the
bending and my rebending.
Is this, in fact, a problem with cast brass and if so, how to anneal it?
I'm a little leary of just playing the torch on it. Could the kitchen oven
be used for this? It can be set as high as 550 F. ? Would that high enough
to anneal brass? It's a self cleaning gas oven but I don't have any idea
what the temperatures run to in the cleaning cycle but have wondered if that
might be useful for this sort of job or even drawing steel. Thoughts?
