Environmentally friendly, pollution-free heat treatment for the Earth! A new type of nitriding method that exhibits excellent properties.
Acid nitriding is a nitriding method that differs from conventional nitriding methods by adding an appropriate amount of oxygen or air to ammonia gas. Our acid nitriding is based on the ON process and includes three types of processes: ONO, ONOR, each with excellent characteristics. Compared to gas soft nitriding, acid nitriding shows almost the same properties in wear resistance and fatigue strength, but it has the added features of excellent corrosion resistance, seizure resistance, compatibility, and a beautiful black appearance. 【Features】 ■ Pollution-free heat treatment ■ High surface hardness and excellent wear resistance ■ Improved fatigue strength due to surface residual compressive stress ■ Enhanced compatibility and seizure resistance due to the porous acid nitriding layer formed on the surface ■ A beautiful glossy black appearance is achieved *For more details, please refer to the catalog or feel free to contact us.
