Nitriding furnace is a heat-treatment device for surface hardening of metal workpieces. It operates by heating workpieces to a specific temperature in a sealed chamber filled with ammonia gas or nitrogen-rich media. Nitrogen atoms diffuse into the workpiece surface to form a hard nitride layer. It has multiple structures like pit-type and horizontal types, and the nitrocarburizing furnace, a variant, introduces carbon atoms simultaneously to enhance both hardness and corrosion resistance of the surface. We are a professional nitriding furnace manufacturer in China.

Nitriding furnace is widely used in industries requiring high surface hardness and wear resistance. It is essential in automotive manufacturing for crankshafts, gears and camshafts; in aerospace for turbine components and landing gear parts. It also serves tool and die making, bearing production, and heavy machinery sectors. Additionally, it applies to precision instrument manufacturing and military equipment processing, extending the service life of core components.
