Zusammenfassung:	The present invention provides a carbon-coated steel material and a manufacturing method therefor, wherein the carbon-coated steel material has oxidation resistance, sour resistance, and hydrogen induced cracking resistance and can be formed utilizing an existing tempering heat treatment process for a steel material. According to an embodiment of the present invention, the manufacturing method for the carbon-coated steel material may comprise the steps of: subjecting a steel material to tempering heat treatment by heating; and injecting gasified benzene in a state in which the steel material is heated, to form a carbon coating layer on the surface of the steel material. La présente invention concerne un matériau en acier revêtu de carbone et son procédé de fabrication, le matériau en acier revêtu de carbone ayant une résistance à l'oxydation, une résistance à l'acide et une résistance à la fissuration induite par l'hydrogène et pouvant être formé à l'aide d'un processus de traitement thermique de revenu existant pour un matériau en acier. Selon un mode de réalisation de la présente invention, le procédé de fabrication du matériau en acier revêtu de carbone peut comprendre les étapes consistant à : soumettre un matériau en acier à un traitement thermique de revenu par chauffage ; et injecter du benzène gazéifié dans un état où le matériau en acier est chauffé, pour former une couche de revêtement de carbone sur la surface du matériau en acier. 본 발명은 강재의 기존 템퍼링 열처리 공정을 활용하여 형성할 수 있는, 내산화성, 내사워성, 및 수소유도균열 저항성을 가지는 탄소피복강재 및 그 제조방법을 제공한다. 본 발명의 일 실시예에 의하면, 상기 탄소피복강재의 제조방법은, 강재를 가열하여 템퍼링 열처리하는 단계; 및 상기 강재가 가열된 상태에서 가스화 벤젠을 주입하여, 상기 강재의 표면에 탄소 피복층을 형성하는 단계;를 포함할 수 있다.
