Neutral Hardening / Through Hardening

Quench & Temper for High Strength Steel

Through hardening (sometimes referred to as neutral hardening or “quench & temper”) is a hardening process which achieves a required surface and core hardness specification adjusting furnace atmosphere’s carbon potential the same as heat-treated ferrous material’s carbon concentration. In neutral hardening the chemical composition of the surface of the steel is not changed so the heat-treated products are not enriched or decarburized after the process. This method provides the steel with high strength and ductility throughout.

At Tri-City Heat Treat, we have a variety of process types available, thus allowing for the hardening of a wide range of materials. Our 57,000 square foot facility and equipment offers increased capacity and world class hardening services for our customers.
