Aitec's "Nitriding Hardening" is a surface hardening heat treatment method that allows nitrogen to penetrate and diffuse into steel, followed by quenching from the austenite state, resulting in low distortion and unique properties. This heat treatment method involves the infiltration and solid solution of nitrogen into steel in the austenite region (γ) of the Fe-N2 phase diagram. It is then rapidly cooled 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 due to ammonia quenching - High surface hardness of HMV800 or more even with SPCC materials - 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 Case Studies ◆ How to View: From the YouTube link at the bottom of this page *For 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 permeate and diffuse into steel, followed by quenching from the austenite state. Distortion is associated with quality issues, as well as challenges related to polishing labor and costs due to distortion correction. By reducing the distortion itself, total cost reduction can also 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 a proven example 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.

The "carburizing quenching" heat treatment for gears and tooth gears is characterized by low distortion and contamination, making it suitable for heat treatment of gears in reducers and motors. Additionally, because it uses semi-hot oil, the amount of change is minimal, making it ideal for parts of FA equipment that require precision. 【Features】 ■ Capable of handling depths up to 1mm ■ Minimal change due to the use of semi-hot oil ■ Compatible with both gas carburizing and vacuum carburizing ■ Other treatment methods can be proposed according to specifications and requests *For more details, please contact us directly.

Aitec's "gas soft nitriding treatment" is a heat treatment with minimal distortion and contamination. Typically, gas soft nitriding treatment uses oil cooling (cooling by immersion in oil) after heat treatment, but Aitec's gas soft nitriding treatment features air cooling (natural cooling with air), resulting in less contamination. 【Aitec Gas Soft Nitriding Treatment Features】 ■ A heat treatment method with minimal distortion ■ Less contamination due to air cooling instead of oil cooling *For more details, please contact us directly.

This is a new surface hardening heat treatment method that allows nitrogen to penetrate and diffuse into steel, followed by quenching from the austenite state. By introducing nitrogen and performing quenching, a surface hardness of approximately 850 HV can be achieved even with inexpensive SPCC material, and it is possible to increase hardness within the range where nitrogen has diffused internally. The amount of distortion is about half that of carburizing and nitriding quenching, and only slightly larger than gas soft nitriding. The friction coefficient and seizure surface pressure are almost equivalent to those of carburizing and nitriding quenching, while the wear amount is half that of carburizing nitriding materials and one-third that of gas soft nitriding materials, which is quite favorable. 【Features】 - The surface roughness of the samples after treatment is good. - The time required for treatment can be significantly reduced to about 1/3 to 1/4 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 also been demonstrated. *For more details, please refer to the catalog or feel free to contact us.
