[TheForge] Pipe nomenclature

[Dave Brown]

I was at the steel yard this morning and came across something had me 
stymied.  The yard rats didn't, and usually don't, know anything about 
different grades of steel and pipe.  So, I figure this is as good a place 
as any to ask ....

I found some 36" pieces of 6" diameter pipe.  It had printed lengthways ... 
"TURKEY HEAT   ASTM ??" <?? means it was quite illegible, but I think it 
may have been 52 or 56 or 6<something>.  Anyone got a clue?  In spite of 
the "turkey heat" labeling, I'm sure it has nothing to do with Thanksgiving.
