I have been meaning to have my RDs Austempered and maybe cryo-soaked... Thom, did your Bainitic RD9 give up any edge retention or abrasion resistance? Just curious. Or gain any, for that matter... Would there be any toughness gain in trying to get more bainite in S7 (i think it already forms some lower bainite when quenched "normally", ie mar-quenched, right?) Nice to see you here, by the way Thom...
