Well, Shapiro doesn't have any 4140 so local pick-up is out. A few places I checked only have round stock up to 1-3/4". So I went to Speedy Metals web site to have a look. They have plenty of it in the larger diameters.
But now I'm faced with too many choices.
4140 hot rolled - annealed
4140 hot rolled - hardened
4140 cold rolled - annealed
4140 cold rolled - hardened
And just for good measure, let's throw in some 41L40 as well.
Mystery metal is sounding better all the time!
