Abstract

본 발명은 도금밀착성이 우수한 고망간강 및 이로부터 용융아연도금강판을 제조하는 방법에 관한 것이다. 본 발명의 일측면에 따른 고망간강은 중량%로, C: 0.3~1%, Mn: 8~25%, Al: 1~8%, Si: 0.1~3.0%, Ti: 0.01~0.2%, Sn: 0.06~0.2%, B: 0.0005~0.01%, 잔부 Fe 및 기타 불가피한 불순물로 이루어지는 것을 특징으로 한다. 본 발명은 높은 강도와 가공성을 가지면서도 망간으로 인하여 발생할 수 있는 미도금을 방지함으로써 표면 품질까지 우수한 고망간 용융아연도금강판을 제공할 수 있다.
