NOTES: |
A - |
Mechanical property data represents average values derived from laboratory specimens produced under production conditions. |
E - |
Impact strength values are from un-notched Charpy Impact specimens. |
| |
B -
C - |
Elongation is given as inch/inch in one inch (1") gauge length.
Additional data is being developed. |
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 micro-hardness tester because of the porosity in the structure. |
| |
D - |
Yield and ultimate tensile strength values are approximately the same in the heat treated condition. |
G - |
Magnetic induction, Bmax, and remanence, Br, and derived from standard BH curves with a 15 Oersted magnetizing force. Higher Bmax values are obtained at higher magnetizing forces. | |
