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.
