The little test specimens I made were not for case hardened steels but alloy steels.
I have no idea how the tests were done for the case hardened 1020 steel I noted. Obviously it was not done in this same manner or the results would have been vastly different. If the test part was so small that the "Case" met in the middle then it would have been totally useless for case hardened parts as one would now have a High Carbon steel which was essentially through hardened.
As to who cares "Inquiring Minds Want to Know". "IF" one simply does not care I don't understand why they are still reading on page 5. I totally Skip many threads after about the first page because I have no interest in that particular thread. I am still posting here on page 5 because obviously I do Care.
