Surface hardening heat treatment method "Nitriding Quenching"

Heat treatment technology that finishes thin materials without distortion and with a hard finish! Also accommodates short delivery times.

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.
