Heat Treatment:
Annealing: Uniformly heat at 800-850°C (1472-1562°F), hold for a sufficient period, then cool slowly in the furnace to below 600°C (1112°F) to achieve complete annealing.
Quenching: Preheat gradually to the austenitizing temperature of 980-1020°C (1796-1868°F), followed by rapid quenching in oil or air to attain full hardness.
Tempering: Immediately post-quenching, temper at 180-220°C (356-428°F) for two hours, then air-cool to achieve the desired balance of hardness and toughness.
