Awesome! Thank you for the great explanation. That makes complete sense and I really appreciate the knowledge.
Never accept this answer.
I’ll add to my above, any time you are trying to harden low carbon steel, a water quench is usually REQUIRED. I made it sound like an option above, but it IS likely necessary for case hardening.
Thanks again @stimpsonjcat. I agree I hate that answer. I knew there had to be a reason and I couldn’t have been the first person to ask. I just figured it was their way of saying I don’t know.
That is why you never accept that answer, it means exactly that…they don’t know. Knowing is half of making.
