... develops full hardness. Hardnesses of Rockwell C 61-63 should result from such treatment. Lower hardnesses are attained by increased tempering tempera- tures, but for some applications this alloy should not be tempered in the range of 800.105OoF due to a tendency toward temper brittleness. If tempered...
