湘南窒化工業 Product Lineup

Our company conducts gas soft nitriding treatment, which involves heating and holding 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 processing 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 steel types ■ 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, as the compound layer formed on the surface of the nitrided layer is dense and difficult to create porosity, leading to further enhancement of corrosion resistance. *For more details, please feel free to contact us.
