Hey Dan,  Bad mouthing A36 again --

 Its yield is rated at 36,000 psi not its tensile.  Tensile is 58-80 ksi.
Chemical Comp. for bar is carbon 0.26-0.29, Mn 0.60-0.90 with a P max of
0.04 and S max 0.05 and Cu at 0.20

Part of the problem is that the yield is a minimum so many mills will ship
stronger / harder material and call it A36.  I think they push or exceed the
80 ksi tensile most of the time. (Yield is often around 50 ksi)   The above
spec are ASTM spec from Engineering Properties of Steel by the American
Society for Metals.  I don't have the data here -- but I think in the
smaller sizes (like us blacksmith use -- bar below 1 inch) the spec are
wider that what I noted above.

Sure would be nice to just get your hands on a good supply of 1018 - 1020
but most of the time is seems to only way to do that is get cold rolled.
Have you ever tried or gotten your hands on some 1006 - 1008 bar?  I think
it only comes round (feed stock for nails) but it would be interesting to
try.
