  • A For rectangular bar, the Distance Between Parallel Surfaces as used in this table refers to the thickness.
    B Elongation values are based on 5.65 times the square root of the area for dimensions greater than 0.10 in. [2.5 mm]. In any case, a minimum gage length of 1 in. [25 mm] shall be used.
    C Yield strength at 0.2 % offset.
