All you would be doing with the process above is putting the steel in a better condition for drilling holes or filing it. You still have to go through the hardening and tempering process afterwards. If you don't need to do any drilling, or a lot of filing, it is really not necessary, as long as your standard heat treat is good. This anneal works best with steels at or over .80/84% carbon, but can be used on lower carbon steels, if your slow anneal does not soften the steel enough for easy drilling. I oil quench only, but I only use 01. Carbon forms balls beginning around 900°, and continuing to the Curie point, non-magnetic, which is 1414°, where it then starts going into solution again. The one draw back to this type of anneal, is that these carbon balls do not go into solution as fast as layered carbon, and need at least a short soak of a few minutes at quench heat, which should be around 1475°, to 1500°, if for simple steels. If not in a temp controlled oven, that would be about 1 or 2 shades of red above non-magnetic. In the case of 01, it needs a 20 minute soak at minimum, whether it is annealed or not, because of the alloys it contains.
