(b) Apparent hardness measures a combination of matrix hardness plus the effect of porosity. Where applicable, the matrix (converted) hardness is also given in parentheses. (c) Fatigue limit for 10 7 cycles from reverse-bending tests (R.R. Moore testing machines). (d) The suffix number represents the minimum yield strength (in ksi) for the material in the as-sintered condition. (e) The suffix number for the heat treated (HT) or sinter-hardened conditions represents the minimum yield strength (in ksi). Tempering temperature for most heat treated materials is 175 °C (350 °F); nickel steels are tempered at 260 °C (500 °F). (f) Yield strength and ultimate tensile strength are approximately the same for heat treated materials.
