PROPRIETARY CPM 1 V Heat Treatments

  • ANNEALING heated slowly and uniform to a temperature of 900 °C, maintain the temperature for 2 hours and allow to cool to 590 °C in the furnace at a cooling rate no faster than 15 °C. It is then further cooled in still air down to room temperature. The typical annealed hardness achieved by a soft annealing is approx. HB190. 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 1065 - 1120 °C. Maximum toughness is attained at a temperature of 1065 °C, whilst maximum wear resistance is attained at the temperature of 1120 °C. In order to achieve a corresponding degree of dissolution of the alloy elements, a minimum heat penetration time of 20 minutes for hardening at 1065 °C is recommended, or 15 minutes for hardening at 1120 °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 case of vacuum heat treatment, due regard is to be given to applying an appropriate quenching rate (at least at 5 bar pressure). For attaining ideal toughness properties it is recommended to apply the 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 CPM® 1 V® is tempered with a temperature range of 540 - 550 °C. SURFACE TREATMENTS it can be nitrided or PVD/ CVD coated.
  • Annealed: Heat to 870-900°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 840-870°C Equalize. Austenitize: 1065-1120°C, hold time at temperature 10-15 minutes. The lower austenitized temperature of 1065°C provides the best impact toughness. Quench: 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 maximum attainable toughness for a given hardened treatment. Temper: Three times at 540-550°C, 2 hours minimum each time.
