Abstract
본 발명은 C : 1.00% 이하, Si : 0.60% 이하, Mn : 0.40-1.00%, Cr : 1.5-3.5%, Mo : 1.3-3.0%, V : 0.5-1.0%, P : 0.020% 이하, S :0.015% 이하, 총 Al(T,Al) : 0.040% 이하, 용존 Al(S.Al) : 0.032% 이하, 총 산소(T.O) : 0.0030% 이하, Ca : 0.01% 이하를 함유하고 Ca/총산소=0.5-1.5 그리고 용존 Al/총 Al≥0.80으로 구성되고 잔량은 대부분 Fe 이며 나머지는 전기로 제강에서 불가피하게 포함될 수 있는 극소량의 불순원소로 조성된 열간 금형 공구강 제조 방법을 제공하여 우수한 강도, 고온경도, 내열성을 얻으며 강중 알루미나(Al2O3) 및 황화망간(MnS) 개재물의 형상제어원소인 칼슘(Ca)을 첨가하여 비금속 개재물의 구상화, 미세와 그리고 균일화를 실현시킴으로서 내충격성과 인성의 등방성을 향상시켰다.The present invention is C: 1.00% or less, Si: 0.60% or less, Mn: 0.40-1.00%, Cr: 1.5-3.5%, Mo: 1.3-3.0%, V: 0.5-1.0%, P: 0.020% or less, S : 0.015% or less, total Al (T, Al): 0.040% or less, dissolved Al (S.Al): 0.032% or less, total oxygen (TO): 0.0030% or less, Ca: 0.01% or less, and Ca / total It is composed of oxygen = 0.5-1.5 and dissolved Al / total Al≥0.80, the remaining amount is mostly Fe and the rest is made of very low impurity elements which can be inevitably included in steelmaking of the electric furnace. High temperature hardness and heat resistance are added, and calcium (Ca), a shape control element of steel alumina (Al 2 O 3 ) and manganese sulfide (MnS) inclusions, is added to realize spheroidization, fineness, and uniformity of non-metallic inclusions, so that the impact and toughness isotropic Improved.
