COOL PLUS Sub-zero Integrated, Fully Automatic Gryogenic Cooling
The patented COOL PLUS technology is available for the entire tempering furnace range. This cryogenic treatment is ideal for stainless steels, high-speed steels, and tools and is performed between quenching and tempering cycles.
Process:
The injection of liquid nitrogen evaporates into gaseous nitrogen in the heating zone.
Surface temperatures range between -40°C and -120°C.
Fully automated and controlled for perfect reproducibility.
Example:
X20Cr13 steel, quenched at 1035°C and cooled to -100°C, achieves a hardness of 690 HV, compared to 640 HV without cryogenic treatment.
Benefits:
- Increased hardness and dimensional stability: Ideal for components that must remain stable under extreme conditions
- Increased hardness: Significantly increases the hardness of corrosion-resistant steels
- Reduced retained austenite: Improves dimensional stability
- Maintained exceptional gloss: Treated parts retain their optical quality
- Reduced tempering times and costs: Increases efficiency and competitiveness
