i was wondering if 52100 is as easy to work with as 10 series. i have only a magnet and my eye to determine proper temps. until someday i build salt rigs with pyrometers i will continue to do only simple steels. so i was wondering if i can work this stuff the way i'm used to. also, can any of you recomend a link or an easy to follow book on alloy, s curves and specs on different steels. kyle stanley
