Precision nitriding treatment (PSN treatment) for small items and thin items such as precision molds.

For small and thin items that do not become brittle, please try Asahi Heat Treatment's precision low-temperature nitriding process (PSN treatment).

Soft nitriding treatment can easily form a nitrided layer of approximately several hundred microns to 1 millimeter, combining the surface compound layer and the internal diffusion layer, within a processing time of a few hours. Therefore, when processing small or thin items of the above sizes, not only the surface but the entire product becomes nitrided, which can lead to brittleness. Our precision low-temperature nitriding treatment (PSN treatment) allows for easy control of nitrogen diffusion by performing the treatment at low temperatures. This enables soft nitriding treatment that retains the toughness of small and thin items. If you wish to achieve soft nitriding while maintaining toughness even for small or thin items, please consider our precision low-temperature nitriding treatment (PSN treatment). 【Other Features】 - Low-temperature treatment (400°C to 530°C) minimizes dimensional changes and deformation. - Subsequent processes such as shot peening and PVD treatment are possible, allowing for synergistic effects through composite treatments. - Improvement of mechanical properties, mainly enhancing wear resistance, fatigue strength, and heat resistance. - Improved release properties in resin molds. *For more details, please refer to the PDF document or feel free to contact us.
