PROPRIETARY ISOTROP Heat Treatments
- Preheating: 220°C/h measured in the core of cavity. First preheating has to be done at Ts˜620°C and hold until Ts-Tc < 110°C Second preheating has to be done at Ts˜830°C and hold until Ts-Tc < 15°C. Austenitization: After second preheating, austenitization should be rapidly increased up to 1030°C and hold 30 min after Ts-Tc < 15°C. Quenching: Quenching shall be performed in oil or pressurized gas. Fast cooling has to be applied from austenitization temperature down to 150°C. Cooling rate, measured at the surface of the cavity, must be at least 30°C/min between austenitization temperature and 530°C. Tempering: A minimum of 2 tempering should be performed immediately after quenching. First tempering should be done at 570°C. Second tempering shall be performed at a temperature depending on required temperature. For a required hardness of 45HRC, second tempering should be performed at 610°C. In both cases, tempering temperature should be hold 2h minimum or 30min per 25 mm of thickness. After tempering pieces should be air cooled to room temperature. When a third tempering is required, it should be done at 550°C.
