CRYOGENIC TREATMENTS SERVICES

If the heat-treat process is done correctly, it is possible to obtain 95% martensite transformation; but the typical result is 70% or less and many tools will be below 50%. The cryogenic process completes the transformation to near 98% - 99% depending on the material. Martensite is the fine-grained structure that transforms from austenite during the quench cycle. It is this desirable fine grain that should be found in all heat-treated tool steels. Cryogenic Treatments are also common in precipitation hardening steels where dimensional stability is required.
