NOTES:
A - Mechanical property data represents average
     values derived from laboratory specimens
     produced under production conditions.
B - Elongation is given as inch/inch in one inch
     (1") gauge length.
C - Additional data is being developed.
D - Yield and ultimate tensile strength values
      are approximately the same in the heat
      treated condition.
E - Impact strength values are from unnotched Charpy
     Impact specimens.
F - Apparent hardness is measured directly using the
     Rockwell scales indicated. The value is always lower
     than the actual metal particle hardness as measured
     by the microhardness tester because of the porosity
     in the structure.
I - Strength constant for bearing bronze, K,=23,000 psi
