PROPRIETARY CarTech Ferrium C61 Alloy Heat Treatments
- Normalizing: Heat uniformly to 1800°F (982°C) and air cool. Annealing: Heat uniformly to 1250°F (677°C), hold for 2 to 8 hours and air cool. Carburizing: Vacuum carburize at 1830°F (1000°C), followed by quenching in gas (1.5 Bar Nitrogen or higher) or oil medium. Quenching: Gas, Oil, Salt. Cold Treatment: A refrigeration treatment at -100°F (-73°C) or lower for 1 hour is recommended. This should be performed with minimal delay after completion of the quench. Straightening: Operations such as shaft straightening (if required) should preferably be done after the sub zero treatment but prior to the temper. C64 achieves full mechanical strength after tempering, and thus trying to straighten parts after tempering will be more difficult. If excessive distortion exists after the solution treatment, quench and sub-zero treatment, then it is recommended to heat the part to 392°F (200°C) in air for 1 hour, hot-straighten the part (temperature determined by amount of force required to straighten part; temperature should be maintained below 700F (371C) to avoid any tempering or decarburization; a small oxide layer may form at this temperature), and allow the component to air cool. The full temper cycle must then be applied. Tempering: Temper at 925°F (496°C) for 6 to 10 hours and air cool. It is preferred that tempering be performed in vacuum but can also be performed in air.
