????? strange....
let me start over
My uncle gave me a giant blade it's 7in wide, 4ft long and 2in thick at the center and tapers down (off what, I don't know). I had cut into workable pieces and was going to see how a heattreat would go. I've only forged 5160 and 52100 and had no problems with it. I don't know if most steel are the same way but it didn't go non-magnetic until it was a bright orange. That's all I can tell you but if anybody knows what I'm using and wants to tell me, i'd could get this nagging thought out of my mind.
