#Material supplied by Stelco Steel, in the form of semi-killed
#hot-rolled 2.5in X 1.25in bar stock. Steel was normalised by soaking
# at 1600F for 30min and then cooled in air.  Specimens were machined
# from near center of bar; 0.375in long, 0.20in diam. test section
#
#Note that Upper yield point is in data below.
