4. Draw the stress vs. strain curves for CSA G40.21 260W steel, 350W steel, and 700Q steel. Draw to scale and on the same diagram, using the specified minimum values in each case. (Suitable scales are: for strain, 10 mm = 0.01 and for stress, 10 mm 50 MPa.) Then, compare the strengths, F/F, ratio, and ductility (final elongation) of the three steels and explain how the steel grade influences strength and ductility. Use Table in Page 7 from the Steel Handbook as necessary and the following information: E Est Eu Material Steel Type Grade GPa GPa (strain- (final hardening) elongation) Carbon steel rolled 260W 200 5 0.020 0.25 shape steel High-strength low rolled 350W 200 5 0.015 0.25 alloy carbon steel shape steel Heat-treated Plate 700Q 200 2 0.005-0.01 0.15 constructional alloy steel steel 4.
