EN40B is a chromium-molybdenum nitriding steel usually supplied in the hardened and tempered condition, which offers high wear resistance together with good toughness and ductility. It is characterised by its suitability for nitriding, which can give a hard wear resistant core in the range of 61-65Rc. The relatively low temperature of the nitriding process produces components with a scale free surface, and minimum distortion.
Technical Data:
Material is usually supplied in the hardened & tempered condition in which state it is readily machineable, offers high wear resistance and has good toughness and ductility.
After Nitriding, a minimum surface hardness of 750 Vickers (VPN), equivalent to 62 Rockwell is achieved.
