고온용 페라이트계 연철High Temperature Ferritic Soft Iron

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 온도의 함수로서 열 B,E,G 및 H의 인장 면적 감소를 도시한 그래프.FIG. 1 is a graph showing the decrease in tensile area of columns B, E, G and H as a function of temperature.

제2도는 온도의 함수로서 열 B,E,G 및 H의 파괴강도를 도시한 그래프.2 is a graph showing the breakdown strengths of the columns B, E, G and H as a function of temperature.

제5도는 ETB면역 영역이 도표축과 선 사이로 한정되고 Mg+4.5 S=0.07인 상태에서, 마그네슘과 황 함량에 대해 페라이트계 연철의 고온 연성의 의존 관계를 도시한 그래프.5 is a graph showing the dependence of the high temperature ductility of ferritic ductile iron on magnesium and sulfur content, with the ETB immune region defined between the chart axis and the line and Mg + 4.5 S = 0.07.
