    Our Services

    Southwest Heat Treatment Plant

    Quench and Tempering

    Our furnaces are capable of performing austenitizing, quenching and tempering of material to increase the hardness and strength of the material.

    Southwest Heat Treatment


    A specialized heat treatment that alters the microstructure of a material by austenitizing and slow cooling used to homogenize material along with reducing hardness and making the material more workable.
