Gas Soft Nitriding Treatment (SN Process)

For improving the wear resistance, fatigue strength, and sliding performance of steel materials, gas soft nitriding treatment is recommended.

This is an introduction to the gas soft nitriding treatment (SN process) conducted by our company. When gas soft nitriding is performed, a compound layer (ε layer) of about 5μm to 20μm is formed on the metal surface. This compound layer consists of a layer made of nitrides and carbides, and the gas soft nitriding treatment is conducted in an atmosphere that contains not only nitrogen atoms but also carbon atoms. Furthermore, inside this compound layer, a layer of nitrides called the diffusion layer is formed, and these compound and diffusion layers enhance the wear resistance, fatigue strength, and sliding performance of steel material components. For this reason, it can be said that this is a widely used surface heat treatment for automotive parts, electronic components, general industrial equipment, molds, and more. 【Features】 ■ Shapes that are unsuitable for salt bath nitriding or plasma nitriding, such as deep holes and slits, can be easily treated. ■ The surface has a clean, milky white finish without the adhesion of impurities or oxide films. ■ Easily applicable from small lots to mass production, for both small and large parts. ■ Improvement of mechanical properties: enhanced wear resistance (effect of high hardness and low friction coefficient of the compound layer). *For more details, please refer to the PDF document or feel free to contact us.

Technical Introduction: "Gas Nitriding Treatment"

With precise control, it is possible to create products with a small distortion and a high-quality nitride formation layer!

Gas soft nitriding treatment is one of the soft nitriding methods developed to solve the quality issues associated with traditional salt bath nitriding and to reduce environmental impact while achieving equivalent or superior quality characteristics. Generally, at a treatment temperature of around 570°C, a mixed gas primarily composed of ammonia gas is added to form a compound layer of carbides and nitrides on the surface of the processed material, creating a diffusion layer beneath it. This nitrided layer significantly improves the mechanical properties of steel components, such as wear resistance, corrosion resistance, and fatigue resistance. Gas soft nitriding treatment is an environmentally friendly method that allows for effective quality characteristics to be obtained in a short time, making it a processing method that takes environmental aspects into consideration. It is also a treatment method that responds to the lightweight and miniaturization of components due to the spread of electric vehicles, and it is expected to be increasingly applied in a wide range of markets as a surface hardening method. ● For more details, please contact us.

[Case Study] Proposal for Heat Treatment Method for Prototypes

Solutions for precision and distortion issues! Introduction of heat treatment examples for prototypes.

This is a case study regarding a request for heat treatment "salt quenching" for SK material prototypes. 【Consultation Details】 We want to achieve a hardness of HRC50 or higher, but if we perform salt quenching with the material as is, issues with precision and distortion arise. 【Solution Case】 We proposed changing the material from SK to SPCC and altering the heat treatment method to gas nitriding. This not only achieved a hardness of HRC50 or higher, but also reduced the total cost of mass-produced items and improved the lifespan of the molds. At Meinetz, we propose heat treatment solutions tailored to our customers' needs.

Minimize deformation! Heat treatment "Gas Nitriding"

For heat treatment, go to Meinetz! The heat treatment "gas nitrocarburizing" improves corrosion resistance and wear resistance.

Even for shafts that are prone to distortion, warping, and deformation, precise heat treatment is possible with Meinetsu's years of expertise and the latest processing method, "gas soft nitriding treatment." The "gas soft nitriding treatment" is a heat treatment that maintains a temperature range of 550 to 600°C in a mixed atmosphere of carburizing gas and NH3 (ammonia), allowing nitrogen and carbon to diffuse into the surface to form carbonitrides, thereby achieving surface hardening. Additionally, because it operates in a temperature range that does not involve changes in metal structure, it results in a treatment that is less prone to deformation and dimensional changes. This method is actively adopted for sliding parts, wear-resistant components, and resin molds. 【Features】 ■ Strongly enhances wear resistance and corrosion resistance ■ Effective in suppressing distortion, suitable for products with strict dimensional accuracy ■ Adopts retort outer cooling method to reduce load on products ■ Minimal nitriding unevenness, resulting in a beautiful (silver-gray) finish ■ Capable of handling sizes up to Φ600mm × 1000mm

"Gas Nitriding Treatment" that solves your problems during the hardening process.

For sliding parts, wear-resistant parts, and resin molds! Solve distortion, finishing, and cost issues during hardening with "gas nitriding treatment"!

Gas soft nitriding treatment is a heat treatment that forms carbonitrides on the surface by heating and holding in a mixed atmosphere, allowing nitrogen and carbon to diffuse into the surface. It features excellent wear resistance, less distortion compared to quenching, and surface hardness equivalent to that achieved during quenching, with a quicker finishing time. By hardening relatively inexpensive materials, it is also possible to achieve the same hardness as more expensive materials. Additionally, while the basic finishing characteristics such as hardness remain unchanged between "salt bath soft nitriding" and "gas soft nitriding," gas soft nitriding results in a cleaner appearance after treatment, leading to fewer processing steps and faster completion. Products that are treated with salt bath nitriding should also be considered for gas soft nitriding. 【Features】 ■ High wear resistance and corrosion resistance ■ Effective for products with strict dimensional accuracy due to minimized distortion ■ Adopts a retort outer cooling method to reduce the load on the product ■ Minimal nitriding unevenness, resulting in a beautiful (silver-gray) finish ■ Suitable for sliding parts, wear-resistant parts, and resin molds We can accommodate requests for one-off or small-lot heat treatments for prototyping and development. For more details, please refer to the materials available for download in the [PDF download] or feel free to contact us.

Surface hardening method of salt bath soft nitriding "Isonite treatment" [Improved wear resistance]

Integration of structural materials eliminates the need for bearing materials! "Isonite treatment" significantly enhances the wear resistance of steel materials.

"Isonite treatment (low-temperature salt bath nitriding)" is a surface hardening method that forms a nitrided layer on the surface of metals. The compound layer on the surface of steel treated with Isonite has high hardness and consists of fine non-metallic phases, resulting in an extremely low friction coefficient and a property that allows it to easily adapt to its counterpart. Therefore, it achieves exceptionally high wear resistance. 【Features】 ■ Improved heat resistance and wear resistance ■ Increased fatigue strength ■ Enhanced resistance to thermal cracking ■ Improved corrosion resistance ■ Significant contribution to rationalization and cost reduction *For more details, please download the catalog or contact us.
