Rebar
In case anyone was wondering, rebar is indeed any composition. Tonight I
was forging on some and out of curiosity, cheezily heat treated one end (brought it to orange heat, quenched, reheated for a little longer than it took the water to boil off to sorta temper). Took a strike with the hammer and sure enough it broke. Spark test reveals something like 1040 but it must have some other alloying elements since it bears some resemblence to higher alloy steel (wrench stock for instance). So yes, it's real crappy material. On the other hand. It can be hardened. What a scary thought, toolbits forged from rebar. Hmmmm. But still........
