The finishing skin is good! The processing time is short, and a 20μ curing layer can be obtained in 40 minutes.
"N-Quench (Nitriding Quenching)" is a treatment method that allows nitrogen to penetrate and dissolve in steel within the austenite region of the Fe-N phase diagram, followed by rapid cooling to obtain hard nitrogen martensite. In nitriding quenching, the nitrided layer hardens into nitrogen martensite due to rapid cooling, but the interior does not harden because it is cooled from below the transformation temperature of the Fe-C system. Furthermore, the thermal treatment distortion (dimensional change) is comparable to that of gas soft nitriding. 【Features】 ■ Hardness of HV800 or higher can be achieved even with low carbon steel. ■ The amount of gas used is extremely small, about 1/10 of that used in gas soft nitriding. ■ Processing time is short, with a hardened layer of 20μ obtained in 40 minutes. ■ The finish is good. ■ The treatment is environmentally friendly. *For more details, please refer to the PDF document or feel free to contact us.
