PROPRIETARY OCR8W 物理性能
PROPRIETARY OCR8W 热处理
- Soft Annealing: When used after reforging, spheroidized annealing has to precede hardening. Annealing must be performed after hot working and before rehardening. Heat at a rate not exceeding 50°C per hour to reach 820 - 860°C, and hold at that temperature for 1h/25 mm thickness; 2 hours minimum. Then cool down slowly in the furnace to 600°C at a rate not exceeding 20°C/1h. Continue cooling to ambient temperature in the furnace or in air. Hardening: Preheating - Heat at a rate not exceeding 50°C per hour to 620 - 680°C for equalization, and then continue heating to reach 820 - 840°C. For normal tools, use only the second temperature range as a single preheating treatment. Austenitizing - Heat rapidly from the preheat. Furnace or salt bath: 1040 - 1080°C. Equalize and soak at austenitizing temperature for 30 minutes for pieces up to 25 mm in thickness, plus 15 minutes for each additional 25 mm of thickness. For maximum toughness, austenitize from the lower recommended range of austenitization temperatures. For maximum wear resistance, austenitize from the upper recommended range of austenitization temperatures. Quenching: 1040 - 1080°C / air, oil or inert gas. To increase hardness by 1 - 2 HRC and dimensional stability after quenching, a sub-zero treatment may be used. Tempering: Temper immediately after quenching (when material after quenching reaches 90 - 70°C). At least two tempering treatments are recommended to achieve a uniform tempered microstructure. Slowly heat to reach tempering temperature. Holding time in the furnace: 1h for every 25 mm of workpiece thickness, but 2h minimum. This is followed by cooling in air. Typical tempering temperatures are 150 - 550°C.
