The present invention relates to a steel material for a vessel provided with a brittle crack prevention device to which a heating member capable of increasing a design temperature of a steel material applied to a welding structure such as a containership and an LNG storage tank may be installed. According to the present invention, the heating member is installed in the steel material used in a large welding structure such as a large containership, the LNG storage tank, and the like such that the design temperature of the steel material can be increased. In addition, the steel material can be used against a usage of a steel material thicker than a current status or even a stronger regulation. The heating member may be composed of an insulating material, a heating device, or both of the insulating material and the heating device.
본 발명은 취성균열 방지장치를 구비한 선박용 강재에 관한 것으로서, 컨테이너선과 LNG 저장탱크와 같은 용접구조물에 적용되는 강재에 설계온도를 높일 수 있도록 히팅 부재가 장착될 수 있다. 본 발명에 따르면, 대형 컨테이너선, LNG 저장탱크 등의 대형 용접구조물에 사용되는 강재에 히팅 부재를 장착하여 강재의 설계온도를 올릴 수 있을 뿐만 아니라 현재 수준보다 더 두꺼운 강재를 사용하거나 더욱 강한 규제가 발효시에도 이를 회피할 수 있는 효과가 있다.
