Cryogenic (Sub Zero) treatment process is the process in which, a ultra-low temperature of about – 196°C is used to treat the tool steel to enhance their desired metallurgical and mechanical properties. Ultra cold temperatures are achieved using computer controls, a well-insulated treatment chamber and liquid nitrogen (LN2). This process is completely eco- friendly and actually help reduce waste.
The treatment helps to remove retained austenite from the quenched components or tools. As a result, this increases the wear resistance of the tools or stabiles the component.
The entire process takes between 36 to 74 hours, depending on the weight and type of material being treated. Most importantly the process is not just a surface treatment but it affects the entire mass of the tool or component being treated. Consequently making it stronger throughout. In conclusion, the hardness of the material treated is unaffected, while its strength is increased.
– Reduced maintenance, repairs and replacement of tools and components
– Reduced vibrations
– Rapid and uniform heat dissipation
– Improved conductivity
