Nitriding Heat Treatment

Unlock Superior Performance with Nitriding Heat Treatment Services

Explore the exceptional benefits of our Nitriding Heat Treatment services, a specialized process designed to fortify the surfaces of ferrous materials through the infusion of nitrogen atoms at sub-critical temperatures. This transformative method results in the creation of a robust, wear-resistant, and fatigue-resistant nitrided case beneath the surface. Nitriding heat treatment emerges as a strategic choice for precision parts, offering a unique blend of subcritical temperatures, minimal distortion, and protective atmospheres.

Our Nitriding Heat Treatment Expertise

We specialize in providing Nitriding Heat Treatment for a diverse range of ferrous materials. While theoretically applicable to most ferrous substances, the process reaches its zenith when applied to alloy steels enriched with nitride-forming elements such as Cr, Al, Mo, V, W, and Ti. Optimal hardness response is achieved by selecting "nitriding steels" like 4130, 4140, 4150, 4340, Nitralloy 135, and 8640, allowing nitrogen to form alloy nitride precipitates and enhance case hardness. Chrome and chrome-vanadium steels, including the 51xx, 52xx, 61xx families, prove to be excellent candidates for nitriding. Frequent nitriding of tool steels, such as H-1, H-13 hot work, D-2 cold work, and P-type mold steels, ensures optimal performance. High-speed tool steels and stainless steel, with a necessary surface activation step, undergo effective nitriding. Additionally, some nickel-based superalloys qualify for our advanced nitriding services.
