Heat Treatment:
Annealing: Uniformly heat the steel to 800-850°C (1472-1562°F), hold for a sufficient duration, then gradually cool in the furnace to below 600°C (1112°F) to achieve complete annealing.
Quenching: Preheat slowly 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 after quenching, temper the steel at 180-220°C (356-428°F) for 2 hours, then air cool to obtain the optimal balance of hardness and toughness.
