For prototyping and development! Precision heat treatment "gas nitriding" for single items and small lots.

Ideal for prototyping and development! Heat treatment "gas nitriding" improves corrosion resistance and wear resistance. *We can accommodate single items and small lots!

"Gas soft nitriding treatment" is a heat treatment process 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 and achieve surface hardening. By leveraging the characteristics of the Unizof method, it can perform precise heat treatment without inconsistencies, even for one-off and small lot products. It is actively adopted for heat treatment in prototypes, development, and one-off or small lot products, such as sliding parts, wear-resistant components, and resin molds. **Features** - Strong improvement in wear resistance and corrosion resistance - Effective in suppressing distortion, suitable for products with strict dimensional accuracy - Adopts retort peripheral cooling method to reduce the load on products - Minimal nitriding unevenness, resulting in a beautiful (silver-gray) finish - Capable of handling sizes up to Φ600mm × 1000mm

[Case Study] Proposal for Heat Treatment Method for Prototypes

[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.

"Gas Soft Nitriding Treatment by the Unizoff Method" *Heat Treatment Case Studies Now Available!*

"Gas Soft Nitriding Treatment by the Unizoff Method" *Heat Treatment Case Studies Now Available!*

Improved corrosion resistance and wear resistance! "Gas soft nitriding treatment" using the Unisof method.

Gas soft nitriding treatment is a heat treatment process 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 and achieve surface hardening. The Unizoff method generates this mixed atmosphere through the thermal decomposition gas of urea, creating a consistently stable environment. Compared to salt bath heat treatment, it does not use cyanide salts, making it an environmentally friendly heat treatment method that contributes to pollution prevention. Various set methods can be chosen according to the product, such as direct placement on fixtures, hanging, or alignment. Additionally, gas soft nitriding treatment using ammonia gas is also available upon request. 【Features】 - Strong improvement in wear resistance and corrosion resistance - Effective for products with strict dimensional accuracy while minimizing distortion - 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

Minimize deformation! Heat treatment "Gas Nitriding"

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.

"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.
