Yeah, I got all that and think I understand it, but....


:

If, on the other hand, you mean tensile/ a correspondent to ductility in some ferrous metals, in a steel rod- such as re-bar or other structual reinforcement applications, the reading may differ- but the fabrication grade steels ( angle, channel, I-Beam etc.) used in coded construction applications today will average 53,000 psi tensile before rupture- think of the tensile test as a giant taffy pull with calibrations to read in PSI-

....so, a 1/8" piece of 6011 rod will support twenty-five tons before stretching?? I don't believe it.... Am I missing something? I'll be ther first to admit that I have no background in metals whatsoever so I'm quite willing to learn.... but I didn't just fall off the turnip truck so tell it to me in a way that I can believe.
