Description
En36 (655M13) is a nickel-chromium case-hardening steel which is suitable for deep quenching to develop a hard core suitable for gears, cam rollers are only available in diameters. Heat treatment details carburize at 880/930 ° C. Refining at 850/880 ° C cooling in air or water Quenching at 760/780 ° C then quenching in oil Quenching in oil at a temperature of 150/200 ° C this will reduce the stresses and risks of cracking.
