Heat treating is accomplished in the range of 1475 F followed by oil quenching which will minimize distortion more than water quenching. In the 'as quenched' state, it is extremely hard (Rc 65).
Tempering must be done to reduce the hardness and increase the toughness. The normal range of tempering is 400F – 600F. However it can range from 400F to 1200F, depending on the amount of hardness/toughness desired.
For a hardness of Rc45, which would be in the 'spring steel' range, a good starting point would be 425F.
Both the heat treating and tempering should be done in a controlled temperature furnace to assure even heating.
