湘南窒化工業 List of Products and Services

Our company conducts gas soft nitriding treatment, which involves heating in an atmosphere of "ammonia gas + N2 + CO2" at 560 to 580°C for 2 to 5 hours to achieve effective nitriding in a short time. This method, which simultaneously allows the diffusion of (M) and (C), is accurately referred to as gas carburizing nitriding. However, due to the low treatment temperature of 570°C, the infiltration of (C) is minimal, resulting in a significant nitriding effect from the infiltration of (N). 【Features】 ■ Applicable to all types of steel ■ Minimal nitriding unevenness and no surface roughness ■ Short processing time of 5 to 10 hours ■ Prevention of nitriding ■ Improvement in corrosion resistance due to the prevention of nitriding; the compound layer formed on the surface of the nitrided layer is dense and less prone to porosity, leading to further enhancement of corrosion resistance. *For more details, please feel free to contact us.
