Ed -- does it list anything for nitronix? I've got a couple of pieces. It was used in downhole oil field tools. I haven't worked it yet. I understand it is real tough, as in get a bigger hammer!

Thanks,
Reynolds

Hi Chuck, Lucky me, the friendly instructor at the nondestructive testing department at the local Vo-tech lent me a copy. If anyone needs some information on a specific alloy, let me know soon I have to return it. And if you don't mind, let me know what tool steels you guys like best so I can make a copy of that info. before it's gone. Thanks, Ed P.S. I'm already planning on getting O1, S1, S7, H13, 5160 & 4140 ----- Original Message ----- From: "Chuck Robinson" <[email protected]> To: <[email protected]> Sent: Tuesday, August 26, 2003 11:39 AM Subject: Re: [TheForge] Heat Treating 5160 was Welding 5160 > Hey Dave, > Bill's book is good, but the bible is the "HEAT TREATERS GUIDE" published by > ASM. > Regards, > Chuck > ----- Original Message ----- > From: "David E.
