Hot Forming
Forging: 1100 to 900℃, slowing cooling in furnace.
Heat Treatment of 1.2367 Steel
Annealing: 800 to 850℃, slow cooling in furnace (10-20℃/hr), down to 600℃, cooling in air. Hardness after annealing: max. 220 HB.
Stress relieving: 600 to 650℃, slow cooling in furnace. Hold in neutral atmosphere for 1 to 2hours.
Hardening: 1020 to 1060℃, oil, salt bath 500 to 550℃, air or vacuum with gas quenching. Hold 15 to 30 minutes. Hardness , 52 to 54HRC, in oil or salt bath, 50 to 53HRC in air or vacuum.
Tempering: 520 to 700℃. Slowly heating to tempering temperature right after hardening. Recommended to temper 2 or 3 times to increase toughness.
