  • Thermal Treatments

    Quench & Temper 

    The process is primarily used for ferrous alloys to harden the material by austenitizing and then cooling at a rate that allows for a substantial amount of austenite to transform to martensite. Century Sun Metal Treating offers all major hardening processes to provide this service e.g. salt bath hardening, vacuum hardening, atmosphere hardening etc.

    Induction Hardening

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

    Carburizing 

    Absorption and diffusion of carbon into solid ferrous alloys by heating to a temperature above the Ac3, and providing contact with a suitable carbonaceous material and atmosphere. Carburizing is a form of case hardening that produces a measurable carbon gradient extending inward from the surface.

    Carbonitriding 

    A case hardening process in which a ferrous material is heated above the lower transformation temperature in a gaseous atmosphere that promotes the absorption of carbon and nitrogen by the surface and through diffusion creates a concentration gradient.

    Ion Nitriding 

    Century Sun offers two proprietary surface treatments that are classified as Ion Nitriding, one is CaseTuff* and the other is CaseWear*. This thermal diffusion case hardening process is designed to add significant value by extending tool life on both ferrous and stainless steel grades of material. CaseWear* is designed for cold work applications and CaseTuff* provides a more ductile layer for hot work steels. Distortion is also minimized with this process due to the relatively low temperature which is held below the Ac1 for ferritic steels. Finished tooling and components are common to this process.

    Marquench

    A treatment for ferrous alloys in which a part is quenched from the austenitizing temperature and stabilized before martensitic transformation in order to lower stress and reduce distortion.

    Precipitation Hardening

    Hardening of a material caused by the precipitation of a constituent from a supersaturated solid solution.

    Stress Relieving

    Heating of the work piece to a suitable temperature for the grade of material, then holding the long enough to reduce residual stresses.

    Annealing

    A thermal treatment primarily used to soften metallic materials, but also used to simultaneously produce changes in other properties or microstructure.

    Normalizing

    Heating a ferrous alloy to a suitable temperature above the transformation range and then cooling in air to a temperature substantially below the transformation range.

    Cryogenic Treating

    Our “cold chamber” can accommodate load sizes to 36" x 36" x 50" up to a 4,000 lb. hearth capacity. Thermal processes to -300° Fahrenheit are vertically integrated into the heat treating cycle completely transforming and refining the heat treated microstructure which extends tool life, secures dimensional stability and achieves the optimum mechanical and metallurgical properties obtainable within the industry today.
