| Heat Treatment | H13 / 1.2344 / SKD61 steel Annealing: 750 to 800ºC, slow cooling in furnace (10-20ºC/hr), down to 600ºC, cooling in air. Hardness after annealing: max. 230 HB. Stress relieving: 600 to 650ºC, slow cooling in furnace. Hold in neutral atmosphere for 1 to 2hours. Hardening: 1020 to 1080ºC, oil/air, hold 20 to 30 minutes. Hardness , 52 to 56 HRC in oil, 50 to 54 HRC in air. Tempering: 560 to 580ºC. Slowly heating to tempering temperature right after hardening. Recommended to temper at least twice. The second tempering temperature shall be approx. 20 to 30ºC lower than the first tempering. | ||
