Annealing Air Hardening Steel: The cooling rate is very critical. The book says ... Tempering is the reheating of the part to a temperature well below the hardening temperature to reduce the hardness and increase the toughness. This may range from 350°F to as high as 1350°F depending on the steel and the hardness desired.
