アイテック List of Products and Services

Aitec's "Nitriding Hardening" is a surface hardening heat treatment method characterized by low distortion, which involves the infiltration and diffusion of nitrogen into steel and quenching from the austenite state. This heat treatment method allows nitrogen to infiltrate and dissolve in the austenite region (γ) of the Fe-N2 binary phase diagram. It then rapidly cools to produce hard nitrogen martensite. Unlike conventional "carburizing hardening," this process uses ammonia for quenching, resulting in zero CO2 emissions during the treatment process! It can be proposed as a new treatment method that considers environmental impact. **Benefits of Nitriding Hardening** ★ No CO2 emissions from quenching with ammonia - High surface hardness of HMV800 or more even with SPCC material - Lower quenching temperature than carburizing, resulting in low distortion (with a proven example of 50% reduction in distortion) - High resistance to softening - Total cost reduction without distortion correction ~ "Decarbonized Heat Treatment Nitriding Hardening Seminar" Video Now Available for Free! ~ ◆ Theme: Decarbonized Heat Treatment Nitriding Hardening Seminar Exploring the Possibilities from Carburizing to Nitriding ◆ Available Video: Nitriding Hardening Mass Production & Development Cases ◆ How to View: From the YouTube link at the bottom of this page *For more detailed information, please refer to the technical materials available for download in the [PDF Download] section below.

Aitec's "Nitriding Quenching" is a surface hardening heat treatment method characterized by "low distortion," which allows nitrogen to infiltrate and diffuse into steel and perform quenching from the austenite state. Distortion is associated not only with quality issues but also with challenges related to polishing labor and costs due to distortion correction. By reducing distortion itself, total cost reduction can be achieved. 【Benefits of Nitriding Quenching】 ■ High surface hardness of HMV800 or more even with SPCC material ■ Lower quenching temperature than carburizing, resulting in low distortion (with examples of 50% reduction in distortion) ■ High resistance to softening ■ Total cost reduction without distortion correction ■ No CO2 emissions (environmental protection) [Aitec's Strength 1: Contract Analysis of Heat Treatment Distortion] We analyze the amount of distortion before and after heat treatment using a 3D scanner, allowing for shape comparison before and after treatment. We also accommodate requests for analysis only. [Aitec's Strength 2: Integrated Production] By providing integrated production of pressing and heat treatment, we can guarantee product dimensions. We offer added value by consolidating suppliers. ~ We are also seeing an increase in requests for prototypes and tests.

This is a new surface hardening heat treatment method that allows nitrogen to infiltrate and diffuse into steel, followed by quenching from the austenite state. By allowing nitrogen to infiltrate and then quenching, a surface hardness of about 850 HV can be achieved even with inexpensive SPCC materials, and it is possible to increase hardness within the range where nitrogen has diffused. The amount of distortion is about half that of carburizing nitriding quenching and only slightly larger than gas soft nitriding. The friction coefficient and seizure surface pressure are almost equivalent to those of carburizing nitriding quenching and gas soft nitriding, while the wear amount is favorable at half that of carburizing nitriding materials and one-third that of gas soft nitriding materials. 【Features】 - The surface roughness of the samples after treatment is good. - The time required for treatment can be significantly reduced to about one-third to one-fourth of that for gas soft nitriding. - It has a tempering softening resistance comparable to that of carburizing. - The amount of distortion is about half that of carburizing nitriding. - Superiority in friction and wear characteristics has been demonstrated. *For more details, please refer to the catalog or feel free to contact us.
