Or do I temper it again for the second time? If so,do I still needSo,am I doing the right tempering here? You guys temper for 2 hours,but this one took only 20 minutes.The tempering colors appeared after only 5How are you attaching the dies to the hammer? If you still have any welding to do to attach them that will act as tempering too.You should be ok.JGlenn,Yes,I plan to weld them on a steel plate.Thanks a lot for that thought.Ill probably sprinkle water on the die every now and then while iI'm not an expert,but I have made 3 air hammers and helped build 3 others and the welding should be done with the die material annealed.The die aUh-oh,if this is the case,I guess I need to normalize the dies(3x),weld them up on the plates,then HT again.Daniel Gentile warned me of projeI agree with Peter.Bevel the edges that get welded to the plate to get some more strength.Drilling holes in the plate and plug welding also helps.4140 will be fine right where you have it.Before you weld them onto the plate,clean them up bright,then heat them to blue again.THEN weld themThank you so much gentlemen for all the advice.These dies,and an electric motor are the last pieces to my power hammer project.I will create a nGo one better,make them again from mild steel,keep these other ones for spring dies,and SuperQuench the mild steel ones.Get the near perfect RCEffects of Tempering AISI 4140 Steel in Double- Angle tempering on the mechanical properties and microstructure of 4140 steel described on the Metallurgical Investigation of the Effects of Double Tempering on the Hardness,Impact Toughness and Microstructure of AISI 4140 Steel.The second goal of this project is toSAE AISI 4140 Steel Properties,Material Heat Treatment Dec 14,2019 QuickHardening tempering 4140?#0183;Tempering temperature of 4140 alloy steel can be from 204-649 QuickHardening tempering 4140?#176;C (400-1200 QuickHardening tempering 4140?#176;F) after normalizing and oil quenching,and the corresponding Rockwell hardness can be obtained.
