Title (EN) STEEL FOR CARBURIZING, CARBURIZED STEEL COMPONENT, AND METHOD FOR PRODUCING SAME
(FR) ACIER POUR CÉMENTATION AU CARBONE, ET COMPOSANT EN ACIER CÉMENTÉ AINSI QUE PROCÉDÉ DE FABRICATION DE CELUI-CI
(JA) 浸炭用鋼、浸炭鋼部品、及び、その製造方法
Abstract: front page image
(EN)The present invention is: a steel for carburizing; and a carburized steel component that is provided with a steel section and a carburized layer formed on the outside surface of the steel section and having a thickness of over 0.4 mm and less than 2 mm. The chemical components of the steel for carburizing and the steel section of the carburized steel component simultaneously satisfy a formula for a hardness indicator, a formula for a quenching property indicator, and a formula for a TiC precipitation quantity indicator.
(FR)L'invention concerne un acier pour cémentation, et un composant en acier cémenté qui est équipé d'une partie acier, et d'une couche de cémentation dont l'épaisseur de formation sur une face externe de ladite partie acier dépasse 0,4mm et est inférieure à 2mm. La composition chimique de l'acier pour cémentation et de la partie acier du composant en acier cémenté, satisfait simultanément une formule indicative de la dureté, une formule indicative de la trempabilité, et une formule indicative de la quantité de précipitation TiC.
(JA) 浸炭用鋼、及び、鋼部と前記鋼部の外面に生成した厚さ0.4mm超2mm未満の浸炭層とを備える浸炭鋼部品であって、浸炭用鋼、及び、浸炭鋼部品の鋼部の化学成分が、硬さ指標の式と、焼入れ性指標の式と、TiC析出量指標の式とを同時に満足する。
