Ah hah, I was confusing Farenheit with Celcius... Hmm, interesting. I related toughness to the same brittleness the article speaks of.... Maybe I will have to treat a piece of O1 and give it a whack or two, although I did make a couple new firing pins for that POS Mossberg O/U shotgun they sell and I know they've survived the last 3 years of shooting trap, over a few thousand rounds now I imagine. That's better than both factory firing pins at this point. Oh, and that's a very handy chart!
