I forged and ground a 10" integral chef in 52100, had about 4-5 hours into it already. I should have known, I've made this mistake before- don't grind the damn edge to 20 thous BEFORE heat treat. Well, even with pre-normalization cycles, the edge came out of the quench with massive wave-warping along the edge. Tried all the tricks in my book today, even made up a couple- to no avail, I ended up cracking the edge. AARRRGH. Back to square one tomorrow. Why does it have to be an order that's due on Monday?
