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.
G - Magnetic induction, Bmax, and remanence, Br, are derived from standard BH curves with a 15 Oersted magnetizing force. Higher Bmax values are obtained at higher magnetizing forces.
