Heat treatment with minimal distortion and contamination: "Gas Nitriding Treatment"

Low distortion heat treatment 'gas soft nitriding.' Since it is cooled by air instead of oil, it allows for a clean appearance with minimal contamination.

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.

Attention those troubled by distortion during heat treatment! A new heat treatment method that can also handle thin materials.

Reduce distortion by 50% compared to conventional quenching methods! A new surface hardening heat treatment method, "Nitriding Quenching," that does not distort even with thin materials. *Prototyping and test processing available.

Aitec's "Nitriding Quenching" 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, it is possible to achieve a surface hardness of about 850 HV even with inexpensive SPCC materials, and to increase hardness within the range where nitrogen has diffused internally! ~ Currently recruiting for prototype and test processing! ~ 【Benefits of Nitriding Quenching】 ■ Useful as an alternative surface hardening method for parts ■ Effective for parts requiring low distortion ■ Capable of hardening to the interior ■ Achieves a deeper hardened layer in a shorter time compared to gas soft nitriding treatment *For more details, please view the PDF available for download below or feel free to contact us.

Pipe IH heat treatment + partial thin-walled processing "Netsuren Batted"

Local control of pipe material thickness is possible! Furthermore, it is possible to achieve both lightweight and high strength through induction heating treatment.

Butt-joined processing allows for flexible adjustment of the thickness of pipe materials through inner and outer diameter drawing. It enables inner diameter slimming without cutting! This contributes to weight reduction and material cost savings. Additionally, even in thin sections, performing IH heat treatment provides high strength and high toughness, achieving high bending fatigue strength. Example) "Before processing" Weight: 704g Total length: 300mm ↓ "After butt-joined processing" Weight: 576g Total length: 300mm - Reduction rate: 49% - Wall thickness (thinning): -31.9% - Weight reduction: 18.2%

Surface hardening heat treatment method "Nitriding Quenching" *Prototype and test processing available

Reduce distortion caused by quenching! A new surface hardening heat treatment method that does not warp even thin materials.

"Diffusion Nitriding" 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 introducing nitrogen and performing quenching, 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 internally. At ITEC, we provide a comprehensive service from mold design to press processing, heat treatment, and surface treatment, offering high-precision metal parts backed by extensive know-how. ■ Currently recruiting for prototype and test processing! ■ 【Features】 ■ Good surface roughness of samples after treatment ■ Processing time can be significantly reduced to about 1/3 to 1/4 of that required for gas soft nitriding ■ Has a tempering softening resistance comparable to carburizing ■ Approximately half the amount of distortion compared to carburizing nitriding ■ Proven superiority in friction and wear characteristics *For more details on N-Quench, please refer to the PDF available for download.*
