PROPRIETARY CPM Rex 076 Heat Treatments

  • SOFT ANNEALING it is heated uniformly to a temperature of 860 - 870 °C; maintained at this temperature for 2 hours and allowed to cool to 550°C in the furnace at a cooling rate of 10 °C per hour. This is followed by cooling in still air. The strength values achieved by soft annealing are HB 285/ 310. STRESS RELIEVING follows rough machining by heating to a temperature of 600 – 700 °C. After 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 it usually involves the use of 2 - 3 pre heating stages (450 – 500 °C / 850 – 900 °C / 1050 °C). The material is then rapidly heated from the preheating temperature to the austenitizing temperature of 1150 – 1205 °C. High austentizing temperature results in high elevated temperature hardness while a low austenitizing temperature provides improved toughness. The austenitizing temperature is normally 1180 °C to 1195 °C. We recommend hardening in salt bath. Standard guidelines for conventional high speed steels can be applied. QUENCHING can take place in oil, air or pressurized gas. Hot bath quenching at approx. 550°C is recommended. This provides flaw-free surfaces and avoids the risk of abnormal deformation. Material diameters up to max. 20 mm can be quenched with compressed air or compressed gas (in vacuum furnace, depending on type of furnace). This quenching method is too slow for larger cross-sections and results in the hardness values being too low. Quenching in oil ensures the correct hardness level even for large cross-sections, however, there is a risk of excessive distortion. Quenching large-volume tools in the hot bath generally results in slightly lower hardness than oil quenching. Irrespective of which quenching method is used, in all cases, the tools should be quenched to a temperature below 40 °C. The material must be tempered immediately after hardening. TEMPERING should be carried out immediately after the material has cooled down to below 50 °C or when the tool can be held with two hands. Triple tempering with a holding time of 2 hours in each stage at the tempering temperature is necessary. It is important to ensure that the tools are cooled down to room temperature between the individual tempering stages. SURFACE TREATMENTS it can be nitrided or PVD/ CVD coated.
