PROPRIETARY D2 Heat Treatments
- Austenitization: to minimize deformations and cracking risks, slow heating rates should be used with an homogenization at 750°C (1380°F). Holding time should be ½ hour per 25 mm thickness. The best optimized temperature range is 1020 / 1050°C (holding time 1min/mm).
Quenching: cooling under overpressed gases (nitrogen) shall be preferred to more efficient media such as oil quenching. Oil quenching should be limited to high sections and simple shapes.
Tempering: it is highly recommended to perform several successive temperings (at least two) at 500°C (930°F) and over. It is not advised to perform tempering at low temperature (200°C (392°F)), which may induce a weakening of the tools.
Stress relieving: heating at 650/700°C (1200/1300°F) in vacuum furnace to avoid decarburization (holding time: ½ hour per 25 mm), then slow cooling in furnace.
Annealing: it is possible to perform an annealing to soften (250 HB max) a piece which is already hardened. Heat to 860°C ± 10°C (1580°F ± 50°F), hold ½ hour per 25 mm, cool 60°C/H max down to 780°C (1435°F) or cool 20°C/H max within 780/700°C (1430/1290°F), still air-cooling.
