saintjohnbarleycorn Posted January 7, 2012 Author Share Posted January 7, 2012 great thanks a lot for the info, that helps me understand it a lot better, do you run up to the desired temp in a short time or do you ramp up slower, is this part of the two hour tempering?

pkrankow Posted January 8, 2012 Share Posted January 8, 2012 Once you get the correct temperature dialed in you can set your oven to it and not fiddle about with the experimentation. As long as you are using known material, or at least a piece of material that you have tested, you should be good without intermediate steps. If you are using scrap, you need to test every piece or parent stock. I have some coil springs, pulled from the same vehicle and presumably of the same manufacture and age that act differently when hardened. I can harden one in oil, the other needs water...teach me to cut up a second spring before I was finished with the first! Phil Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted January 10, 2012 Share Posted January 10, 2012 I set the tempering temp then I insert steels, 2 hours later turn it off and a hour or so later return to remove form the oven. I let them cool in the oven. It wont hurt. Quote Link to comment Share on other sites More sharing options...
