침탄 질화, 고주파 담금질, 면압 피로 특성
The invention gear excellent in surface pressure fatigue characteristics than the conventional, continuously variable transmission, constant velocity joint, to provide a steel part and a method of manufacturing such a hub, is made of steel consisting of a particular chemical composition of the high-frequency quenching after carbonitriding treatment as a steel part for processing, and the N concentration in the surface of 0.1 to 0.8% by mass, the sum of the N concentration and C concentration is 1.0 to 2.0 mass%, and the residual austenite volume of the surface is less than 15% by volume, from the surface, is less than the depth of the incompletely hardened layer 5 ㎛, also carbonitriding induction hardening steel components and the manufacturing method, it characterized in that the X-ray diffraction of the surface of the half width is not less than 6.0 degree. Carbo-nitriding, induction hardening, the surface pressure fatigue characteristics
