I would avoid annealing unless I had a regulated oven to do it in. If I had one I would heat the steel to about 1400° and slow cool to help spherodize the carbides. Critical annealing, which you were describing, can cause the carbides to clump into plates which can cause problems with drilling and grinding later. I would stick to normalizing the steel.
