A specialized surface hardening technique called gas nitro-carburizing uses relatively low temperatures to diffuse carbon and nitrogen into the surface of steel components. While reducing distortion, this treatment greatly increases fatigue strength, surface hardness, and wear resistance. Because a compound layer forms on the surface, it also improves corrosion resistance. Our gas nitro-carburizing service produces reliable, high-performance results with superior dimensional control, making it perfect for precision-engineered parts like pistons, valves, gears, and tools.
