Cryogenic Treatment

CB Manufacturing and Certified Heat Treating, Inc. offer Deep Cryogenic Treatment of knives, blades, and other industrial tools, in our in house microprocessor controlled, cryogenic chamber.

During heat treating, steel’s micro-structure transforms from austenite to martensite, which makes the steel much more wear resistant. However, some small pockets of austenite may not transform and this does not allow the knives to perform as well as they can. Deep Cryogenic processing helps change retained austenite to martensite, completing the transformation process.

Our Deep Cryogenic processing is different from conventional cryogenic processing and requires cooling the parts to more than 300° below zero compared to about 120° for conventional cryogenic processing. This process includes cooling the parts at a programmed rate, soaking the parts for up to thirty-six hours, and then an additional tempering operation to relieve any stress that may remain. We combine Deep Cryogenic processing with our state of the art Vacuum Heat Treating capability to offer unmatched metal treating and the best performance possible from your knives and tools.
