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.
