I bought a giant bar of O1 steel from Amtek a while ago, at my current production rate I figure it is 8 years worth of steel for me. Anyway, with the recent talk of inferior steel, I want to check if this is good to go. It was pretty cheap steel, but I haven't had any real issues, but it is nagging at me and I would like to settle it in my mind. I would like to heat treat several coupons and send to someone to hardness test for me. I will pay of course. Not sure if this is where I post such a request?
