I just read the 4140 pre hard thread and now I have a couple questions.
Is the pre Hard the same thing as 4140 HT ? I've always thought it was but maybe I'm wrong ?
What about HTSR ? is there another process involved with the HTSR or is stress relieving just a side benefit of the heat treat process ?
Thanks
