Our Expert Heat-Treating Services

Superior Heat Treat offers a full spectrum of specialized heat-treating processes designed to enhance the performance and durability of your components. Our services are tailored to meet the rigorous demands of the tool and die, machine tool, prototype, short-run production, and military markets. Our unique quenching methods that use multiple quench mediums and highly variable agitation levels can be tailored to minimize size and shape change. In many cases, we have developed recipes that have allowed companies to either reduce or eliminate grind operations on certain surfaces.
