Abstract

본 발명은 양식기, 칼 및 가위 등에 사용되는 중량%로 0.10~0.50% 탄소, 11~16% 크롬을 함유한 마르텐사이트계 스테인리스강 및 그 제조방법에 관한 것으로, 서로 반대방향으로 회전하는 한쌍의 롤과 그 양측면에 용강풀을 형성하도록 설치되는 에지댐과 상기 용강풀 상부면으로 불활성 질소가스를 공급하는 매니스커스 쉴드를 포함하는 스트립캐스팅 장치에서, 중량%로 C: 1.10~0.50%, Cr:11~16%를 함유하는 스테인리스용강을 턴디쉬로부터 노즐을 통하여 상기 용강풀로 공급하여 스테인리스 박판을 주조하고, 상기 주조된 스테인리스 박판을 인라인롤러를 이용하여 5~40%의 압하율로 열연소둔스트립을 제조하는 중탄소 마르텐사이트계 스테인리스강의 제조방법과 그 제조방법에 의하여 제조된 마르텐사이트계 스테인리스강을 특징으로 한다. 본 발명은 탄화물 중심편석을 저감시킴으로써, 라미네이션 결함을 억제시키고, 탄화물 편석부와 미편석부 사이의 경도차가 적어 전체적으로 경도가 균일한 마르텐사이트계 스테인리스강을 얻을 수 있다.
