PROPRIETARY CPM 3 V Tratamiento Térmico
- Heat to 900°C, hold 2 hours, slow cool no faster than 15°C per hour to 595°C, then furnace cool or cool in still air to room temperature. Stress relieved: Annealed Parts: Heat to 595-705°C, hold 2 hours, then furnace cool or cool in still air. Hardened Parts: Heat to 15-30°C below original tempering temperature, hold 2 hours, then furnace cool or cool in still air. Hardened: Preheat: Heat to 815-845°C Equalize. Austenitize: 1025-1120°C, hold time at temperature 20-45 minutes. Quench: Air or positive pressure quench (2 bar minimum) to below 50°C, or salt or interrupted oil quench to about 540°C, then air cool to below 50°C. Salt bath treatment, if practical, will ensure the maximum attainable toughness for a given hardening treatment. Temper: Three times at 540-565°C, 2 hours minimum each time.
- SOFT ANNEALING: Heated slowly and uniformly to a temperature of 900°C; maintain the temperature for 2 hours and allow to cool to 590°C in a furnace at a cooling rate of 15°C per hour. It is then further cooled in still air down to room temperature. The typical hardness achieved by soft annealing is approx. HB 240. STRESS RELIEVING follows rough machining by heating to 600 – 700°C. Once complete heat penetration has been reached, the material is allowed to cool in the furnace to approx. 500°C followed by cooling in air. HARDENING usually involves the use of 2 preheating stages (450 – 500°C/ 850 – 900°C). Immediately following this it is heated to the required austenitizing temperature of 1030 – 1130°C. Maximum toughness is attained tat a temperature of 1030°C, whilst maximum wear resistance is attained at a temperature of 1130°C. In order to achieve a corresponding degree of dissolution of the alloy elements, a minimum heat penetration time of 40 minutes for hardening at 1030°C is recommended, or 30 minutes for hardening at 1130°C. These holding times should be correspondingly adapted for thick or thin-walled material cross-sections. QUENCHING Air, hot bath or interrupted oil quenching can be used. In the case of vacuum heat treatment, due regards is to be given to applying an appropriate rate (at least at 5 bar pressure). For attaining ideal toughness properties it is recommended to apply the hot bath quenching method. TEMPERING Immediately temper after the material has cooled down below 40°C. Triple tempering with a holding time of 2 hours in each stage at the tempering temperature is necessary. Normally it is tempered with a temperature range of 520 – 560°C. SURFACE TREATMENTS can be nitrided or PVD/ CVD coated.
