Abstract
본 발명은 화학조성중 B,Al및 N함량을 제어함에 의하여 충격인성을 향상시킨 Cr-Mo강에 관한 것이다. 본 발명은 Cr-Mo강은 통상의 제조공정인 소준, 소려 열처리를 통해 제조되며, C:0.10-0.17%, Si:0.5-0.8%, Mn:0.45-0.65%, Cr:1.1-15%, Mo:0.45-0.6%, B:0.006-0.0014%, Sol.Al:0.03%이하, N:0.005-0.015%, 나머지 Fe및 불가피하게 포함되는 기타불순물로 구성된다.The present invention relates to Cr-Mo steel with improved impact toughness by controlling the B, Al and N content in chemical composition. In the present invention, Cr-Mo steel is manufactured by the usual manufacturing process, sojun, sorrow heat treatment, C: 0.10-0.17%, Si: 0.5-0.8%, Mn: 0.45-0.65%, Cr: 1.1-15%, Mo: 0.45-0.6%, B: 0.006-0.0014%, Sol. Al: 0.03% or less, N: 0.005-0.015%, remaining Fe, and other impurities contained inevitably.
