- a Tensile specimens are located at T/2 location for bars 0.800 inch and under in diameter or distance between parallel sides
and at T/4 location of larger size bars. The strength of bar, especially large diameter, may vary significantly from center to surface; consequently, caution should be exercised in machining parts from bars over 0.800 inch in diameter since strengths may be lower than design values depending on depth of material removed from surface.
- b The T99 value of 266 ksi is higher than specification minimum.
- c The T99 value of 256 ksi is higher than specification minimum.
