I am working on a project in the shop and need some insight. The part in question will have a final diameter of .874" x 5.900" long with a .435" blind hole running thru the majority of it's length! I will either have to try and source some 4140 htsr or 4140 (4142) pre hard. My question to those with experience is how much distortion can I expect when heat treating , and how much should I leave for clean up afterwards ? Ideally I will be looking 37rC when finished . Thanks in advance, as mentioned I am just looking for " guidelines " and will proceed with caution along this path. This is something I would really prefer to do once as heat treating one piece is $125.00 minimum charge plus shipping. Any input would be appreciated.
