PROPRIETARY SITHERM S361R Heat Treatments

Soft Annealing: heating 50°C/h. Protect against oxidation, scaling and decarburization; annealing temperature 800 - 850°C, min. 4 hours; cooling: 20°C/h, slow in furnace, from 600°C air cooling is possible. Stress Relieving: heating 100°C/h; stress relieving 650°C or 50°C under the last tempering temperature., min. 3 hours; cooling 20°C/h, slow and uniformly in the furnace to prevent formation of additional residual stresses. From approximately 200°C air cooling is possible. Hardening: 25 - 650°C, 150 - 220°C/h, 650 - 850°C < = 150°C/h. Hold in furnace at T = 650°C/850°C until (T surface - T core) <= 110°C/60°C. Austenitizing: 1030 - 1050°C, soaking time: 30 min after soaking of die surface and core: (T surface - T core) <= 12°C/60°C or 90 minutes maximum after die surface reaches the designated hardening temperature, whichever occurs first. Tempering: heating 150 - 250°C/h, 1st: 500 - 540°C. 2nd: Choose working hardness, 3rd: 20 - 30°C bellow 2nd tempering. 1 hour per 25 mm wall thickness based on the furnace temperature. Minimum 2 hours. Cooling: Cool in air or in the furnace to room temperature between tempering cycles.
