Abstract
본 발명의 고인성 쾌삭 경면 플라스틱 금형강의 조성은 중량 %로서 C:0.07~0.25%, Si:0.15~0.90%, Mn:0.70~2.0%, P:0.030% 이하, S:0.05~0.20%, Cu:0.20~0.80%, Ni:2.0~4.0%, Cr:0.6~1.5%, Mo:0.2~0.8%, V:0.05~0.20%, W:0.05~0.18%, Al:0.5~2.0%, Ca:0.001~0.010%의 성분을 가지며 저탄소 Ni-Al플라스틱 금형강인 AISI P21 기본적인 특성인 경도 및 강도를 더욱 개량하기 위해 Ni, Cu, Al에 의한 금속간화합물의 석출, V, W, Mo, Cr에 의한 미세 탄질화물의 석출물로 고강도, 고인성, 고경도화하였으며, 쾌삭 원소인 S, Ca를 첨가하여 절삭성을 더욱 향상시켰으므로 금형의 가공시간과 비용, 금형수명의 향상을 기할 수 있다. 특히, 위항의 합금원소들이 충분한 효과를 발휘하기 위한 최적 열처리조건 도출과 열처리 작업의 단순화로 작업성을 향상시켰기 때문에 본 발명은 정밀가공에 적합한 우수한 고인성 쾌삭 경면 플라스틱 금형강 및 그 제조방법에 관한 것이다.
