Every part or component has its own particular challenges, so every item should be considered individually. But, in general, the most beneficial cryogenic treatment is employed when the part is in its rough form and before final cut, polish or grind. This assumes that the component is in a stabilized and stress relieved condition when critical tolerance cuts are applied. Such parts will not experience the “creep” or “walk” that is often experienced on non-cryogenically stress-relieved parts. Parts that go ”out of round “ or fail to maintain flatness on final machining will benefit from cryogenic stress relief. By using cryogenic stress relieving, manufacturing yields will increase, quality will improve, and tolerances will be held to more exacting specifications.

Parts Conditioning Prior to Extreme Temperature Exposure.

Engineers and designers often want to expose parts that will see hostile temperature extremes to these temperatures before parts are put into service. One example is aerospace components, which are exposed to a wide range of temperature extremes when deployed in space or in other aeronautical applications. Other examples include mirrors, transfer pipes, valve components, and industrial equipment that will see very cold temperatures or cryogenic fluids on a regular or periodic basis.

At NitroFreeze, we can thermal cycle your parts or custom components through a full range of high and low temperature cycles to ensure that they will perform flawlessly in field application.

Lab and R & D Support.

When developing new material solutions, or when applying existing materials to new applications, engineers are often unaware of how exposure to extreme cold may affect the performance of the material.

NitroFreeze not only helps to develop test protocols and procedures for such cold applications, but can also conduct the thermal cycling in our labs.

Our wide range of techniques and materials include using temperature controlled atmospheric chambers (for heating and cooling), immersion of parts in various cryogens, such as liquid nitrogen (LN2), carbon dioxide (CO2), neon (Ne), liquid helium (LHe), as well as using boiling liquids and frozen solids. Our unique capability to provide Liquid Helium Processing permits us to reach temperature as low as 5 K or -450°F the closest practical temperature point to absolute zero. See our page on Liquid Helium Processing for more information on helium applications.
