Heat Treating & Cryogenics

Most Industrial knives are made from a variety of tool and stainless steels depending upon the application. To get the most from a knife, heat treating processes to harden, temper, and convert the base material to a stronger end product are critical to the successful application of a knife.

American Cutting Edge realized that controlling the heat treat of its end products was critical to optimizing their life and performance. We have a comprehensive heat treat division with capability for a wide variety of heat treating processes ranging from Atmospheric carburizing and hardening of steels to vacuum heat treating, a variety of quenching processes, induction hardening, straightening and cryogenics.

By having our own heat treat facility right on our manufacturing campus, we are able to specifically tune the characteristics of our knives to your specific application. Call our engineers for specific advice and help in getting the most from your industrial knives.


We are excited to announce the availability of 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.

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. DEEP CRYOGENIC processing is a microprocessor controlled dry process, which 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.

Deep Cryogenic Processing offers the following benefits:

  • Increases abrasive wear resistance.
  • Changes the knife’s entire structure, not just the surface. Subsequent refinishing operations or re-grinds do not affect the permanent improvements.
  • Increases durability and wear life.
  • Decreases brittleness.
  • Increases tensile strength, toughness and stability coupled with the release of internal stresses.

Ask your American Cutting Edge representative for details and pricing on the exciting process & improvement process.
