I'm thinking of putting together a forge for the purpose of heat treating smallish parts (up to 3" diameter and 6" long, not necessarily at the same time). These would be for machine parts, _not_ blades. I'm looking at 4140 or 1050, but all of the books that I've found so far are all about heat treating tool steel.
Are there any books out there with recommendations for heat treating steel machine steels as opposed to tool steels? Does the list have any guidance for annealing to machine, then hardening back up, such medium-carbon steels?
Thanks.
