Cryogenic Treatment

NADCAP certified; Syracuse Heat Treating uses one Cryogenic unit 36" x 36" x 30" capable of slow cooling to -320°F.  In addition, we have a Cryo-Temper unit (24" x 30" x 36") that can thermal cycle between +500°F to -320°F.

The austenite to martensite transformation is complete in almost all metals at -140°F.  Additional structural and mechanical changes in both ferrous and nonferrous materials occur at cryogenic temperatures.  When cooled slowly, held at -300°F to -320°F for an extended period of time and heated carefully, a wide variety of industrial tools and components have demonstrated significant increase in service life and performance; cutting and forming tools, engine parts, gears, brakes, medical devices, brass instruments, to name a few.  It is important that cooling rate, soak time, warm up and tempering be carefully controlled.  Cryogenic Treatment is not a replacement or substitute for heat treating.  Cryogenic Treatment should follow proper heat treatment. It is best done as a step in the heat treating process; often as a continuation of quench and before temper.
