  • General Heat Treating

    Solution treating of aging T-6 temper.

  • Aluminum Heat Treating

    Aluminum heat treating is an annealing process in which a metal is heated and cooled in an inert atmosphere to inhibit oxidation.

    The result is a surface that remains relatively bright.





  • Carburizing

    Carburizing is a case hardening process that produces a carbon gradient extending inward from the surface, enabling the surface layer to be hardened either by quenching directly from the carburizing temperature or by cooling to room temperature.


  • Carbonitriding

    Carbonitriding is a case hardening process in which a suitable ferrous material is heated above the lower transformation temperature in a gaseous atmosphere of such composition as to cause simultaneous absorption of carbon and nitrogen.

  • Cryogenics

    Cryogenic tempering is a process for stabilizing steel and aluminum.

    Low temperature to -120°F.


  • Degreasing

    Our degreasing services encompasses a process for cleaning parts without heat by using solvents.


  • Bright Hardening

    Bright hardening is an annealing process in which a metal is heated and cooled in an inert atmosphere to inhibit oxidation.

    The result is a surface that remains relatively bright.

  • Flame Hardening

    Flame hardening is a specialty heat treating process that requires advanced levels of operator expertise to understand the flame color and timing.


  • Induction Hardening

    Induction hardening is surface hardening process in which the surface layer of a suitable ferrous work is heated by electromagnetic induction to above the upper critical temperature and immediately quenched.

  • Nitriding Services

    Our nitriding services encompasses highly specialized process using ammonia gas at low temperatures (to minimize distortion) for long periods. The surface of the treated piece absorbs nitrogen.

    The result is a superhard metal with high wear capabilities.


  • Normalizing Heat Treatment

    The process of normalizing heat treatment is the heating a ferrous alloy to a suitable temperature above the transformation range and then cooling the alloy to below the transformation range.


  • Metal Straightening

    We offer metal straightening for round shafts, round bars, tubes, screws and more. Shafts can be straightened from their centers or from their outside diameters.



  • Stress Relieving

    Stress Relieving is the uniform heating of a structure, or portion thereof, to a temperature high enough to relieve the major portion of the residual stresses, followed by uniform cooling.


  • Vacuum Heat Treating

    Vacuum heat treating is the process of performing heat treatment in an atmosphere lacking oxygen. The absence of oxygen in the furnace, eliminates the possibility of scaling during carburization and decarburization.

    The result is a fine bright finish that eliminates…

  • Other Services

    Shot Peen Sandblasting

    A process in which steel shot is used to remove rust, discoloration, flash, burrs, and other surface spots from parts as large as 20 inches long and 12 inches wide. This process does not affect the integrity…
