[QUOTE="Trickymissfit, post: 802284, member: 25383"] good point! There is virtually no steel that dosn't change under heat. Some more than others. I've even seen 4xxx series steels change all over the place in a nitirde process. Looking in the Carpenter manual, they do spec the change outs, but I think that's a lot of guess work. For a heat treat some to get my buisiness, they must be of aircraft quality first. Then I look to see if they can do the exotics, as this gives me an idea what they can and cannot do. I'm lucky as I have two in my area. One is a small shop about ten minutes north of me, but if it's gotta be seriously right I goto one up in Indy. I probably didn't use either one a dozen times as I had access to a state of the art heat treat facility. But I liked the way the one in Indy did air hardening processes best. You are probably a light year more upto date on steels than I am for the most part. I may have delt with some of crazier exotics but you still ahead of the game here. I honestly think the operator doing the draw process is more imortant than the guy doing the initial heat treating and quench processes (also can be extremely critical). I've had a few jobs trashed by the quench tank alone! The best thing I ever did was to order in a good agitating system to seriously circulate the quench oil. Then I brought in Castrol and a couple others to try different oils. I settled on Castrol by the way. gary [/QUOTE]
