Surface hardening heat treatment method "Nitriding Quenching"

Heat treatment technology that finishes thin materials firmly without distortion! Capable of short delivery times.

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.
