Solving conventional issues! Surface hardening heat treatment that reduces quenching distortion and shortens processing time!
"N-Quench" refers to a nitriding quenching process that allows nitrogen to penetrate and diffuse into steel, performing quenching from the austenite state. By introducing nitrogen and performing 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 internally. The amount of distortion is about half that of carburizing nitriding quenching and is only slightly larger than that of gas soft nitriding. Additionally, the friction coefficient and seizure surface pressure are almost equivalent to those of carburizing nitriding and gas soft nitriding, and the wear amount is favorable, being 1/2 of carburizing nitriding materials and 1/3 of gas soft nitriding materials. [Features] ■ Reduction of quenching distortion ■ Pure nitriding: Shortened processing time ■ Soft nitriding: High hardness ■ Applicable to inexpensive steel types, not just specific steel grades *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Other Features】 - Since it does not use carbon-based gases, the surface roughness of the treated sample is good. - The time required for N-quenching treatment is about 1/3 to 1/4 of that for gas soft nitriding, allowing for significant time reduction. - It has a tempering softening resistance comparable to that of carburizing. *For more details, please refer to the PDF document or feel free to contact us.
