"WebMar 7, 2003 · Yeild and Tensile only varied by about 0.1 ksi. Elongation however varied up to 3%. Even with a known prime sheet the steel may vary across the width and length of a coil. 5% (unless you're talking about material with really low elongation anyway) doesnt seem to be very much, esp if you're testing the regular forming grades of steel.
