CHART FOOTNOTES
1 Lbs. per cubic inch @ 68°F (annealed)
2 Elastic modulus in tension x 106 P.S.I.
3.% IACS at
68°F (annealed)
4. BTU per foot per hour per °F at 68°F (annealed)
5. Inches ber inch x 10-6 from 68°F to 572°F
6. Reference specification for strip
7. Ultimate tensile strength x 1000 P.S.I.
8. 0.2% offset yield strength x 1000 P.S.I. Yield strengths are not used or accepted as specifications by brass mills; but because of their usefulness, values are given here for design purpose.
9. % elongation in 2". Elongation values vary considerably with thickness. The rolled temper data given are base on thicknesses ranging from .010" to .035" strip.
10. Approximate Vickers hardness - HV unless otherwise specified.
11. Standard heat treatment 2 hrs. at 600°F (3 hrs. @ 600°F for annealed temper)
12. Standard heat treatment 2 hrs. at 700°F (2 hrs. @ 675°F for TS04)
