Cryogenic Processing by Nitrofreeze
Nitrofreeze houses the instruments and expertise to perform a variety of cryogenic processes. All services listed here serve to maximize part use and reduce costs. We offer the following cryogenic lab processes, each customizable to fit the needs of your parts:
Nitrofreeze® Cryogenic Treatment
Increase durability, improve wear resistance, and relieve stresses in steels and other alloys. Applications in tooling, auto parts, aerospace, electrical, sporting equipment, and more.
Custom Cryogenic Solutions
In addition to its trademark Cryogenic Treatment , Nitrofreeze offers a variety of custom processes to enhance part value and performance.
Thermal cycling
Utilizing custom cryogenic treatment cycles, Nitrofreeze offers Thermal Cycling processes for a range of advanced applications. Nitrofreeze has completed work for U.S. Government agencies, MIL and DOD contractors, universities and private industry.
Uphill Quenching
Uphill Quenching is used for aluminum components to relieve residual stresses created during the manufacturing process. When parts frozen by liquid nitrogen are subjected to rapid heating via extreme temperature gradients, the maximum stress relief benefit is attained.
Helium processing
Nitrofreeze has developed unique capabilities to utilize liquid helium for the most advanced and demanding cryogenic treatments and processes. Our Helium Processing techniques bring parts to temperatures approaching absolute zero (0 Kelvin).
Shrink fitting
Shrink Fitting, or “compression fitting,” is a process that inserts a pin or bushing into a housing or other assembly requiring an extremely tight-tolerance fit. The shrink fitting process can be used as an alternative to conventional press fitting, or more likely, to permit a mechanical fit that otherwise could not be accomplished via the mechanical force of press fitting.
Material Separation
Cryogenic Material Separation uncouples parts by exploiting the different coefficient of thermal expansions (CTE) of products composed of different materials.
