[QUOTE="ntsqd, post: 2135044, member: 93138"] That is the over-shoot that I was referring to. It isn't the element's fault, it is the element's controller at fault. Simply, they're stupid because they don't need to be any better. A PID controller can do a much better job of controlling the temperature. There is a thread here on salt bath annealing where these controls are added to a Lyman lead casting pot to more precisely control the salt's temperature. Seems like there's a very linear relationship between how much a PID controller costs and how well it does the job. Depends on the temperatures involved and the saturation times at the various temperatures, but generally I'd say yes although the difference may be so small that practically it doesn't matter at all. Cryo H-T does change the metal. Hopefully for the better. That is a whole different topic that deserves searching for existing threads before starting another one. Heat-Treating is a lot of science, but there is still some magic to it. Each chief practitioner will have their own tricks and preferred ways of doing things. [/QUOTE]
