Thanks for your response MH.
Just to clarify, would machining the part after heat treat/tempering be considered a post tempering heating?
Would maching post heat treat/tempering be a reason to look for burning or over-heating due to the post machining?
Thanks, TMax
I was wondering if a part calls for Nital Etch on the drawing, but the part was not ground during the manufacturing process, should it still be Nital Etched or Tempesr Etch Inspected? The material is 4340 Steel, AMS6415. Thanks!
