What is Cryogenic Treatment?

Cryogenic Treatment is the process of deep freezing materials at cryogenic temperatures (-300ºF). It has been proven to increase the strength and durability of the material being treated, relieve stress, create a more uniform material, and micro-smooth surface.

What happens during deep cryogenic treatment?

During the process of deep cryogenic treatment, austenite is transformed into martensite, which is then then tempered to change into tempered martensite. In addition, small complex carbides called eta-carbides are precipitated out. This greatly reduces residual stress and promotes "micro-smoothing" of the surface.

What items or materials can be successfully treated?

There are many applications for different materials, which can be treated. Look at the Cryogenic Treatment page for a complete list. If a material that you want treated is not on the list then contact us and we would be more than happy to advise you on whether or not is is a good candidate for Cryogenic Treatment.

Will my materials become more brittle? Will the material become damaged?

No. The strength of the material is actually increased after the process. The molecular structure is "filled in" increasing the strength of the material by up to 400%! Also, the material will not be damaged and it will retain its shape.

Is there a need to re-treat materials after sharpening?

Cryogenic Treatment is a one time, permanent and irreversible process. It is a "through" process, not a surface treatment. In fact, in the case of blades or drill bits, the sharpness will not only last longer, but you will be able to sharpen more times with less removal of material. Each sharpening will demonstrate the benefits of the treatment.

How long does cryogenically treating take?
