What the heck is this steel?

[J. Neilson]

I had a fella drop me off 4 big rods (approx. 10" long, 1 1/2" diameter) that were the "lead screw from a wire EDM machine". Anyone have a clue what this stuff could be?

I have NO idea, but I'll bet Bailey Bradshaw does.

Now there's another fella I'd love to chat with someday. Coldn't catch up with Bailey at the Blade show. Can't complain though, I hate to sit at the table all day, too.

High Strength ACME thread rods are 4140-4350 neighborhood. Makes good dies, hammers, and good San Mai clad...Ed

Thanks Ed. Maybe it's time to make that poll hawk I've been wanting to do.
Appreciate the help.
