Abstract
Abstract The present invention relates to a high-strength, highly wear-resistant, and highly contact-fatigue-resistant steel rail and a production method thereof, and belongs to the field of black steel manufacturing technology. The present invention provides a high-strength 5 and highly fatigue-resistant steel rail, comprising the following chemical components by weight percentage: C: 0.76%-0.86%; Si: 0.6%-1%; Mn: 0.7%-1.5%, Cr: 0.1%-0.5%, and 0.8%sMn%+Cr%s1.6%; V: 0.05%-0.3%, Ni: 0.1%-0.35%, and 0.15%sV%+Ni%s0.4%; Mo: 50.03%; P: 50.02%; S: 50.015%; Fe and inevitable impurities: the remaining content, wherein, the metallurgical structure of the steel rail is fine pearlite + A, where, A is 10 proeutectoid ferrite or proeutectoid cementite, and As2%. The tensile strength of the obtained steel rail is 1,260MPa-1,42OMPa. | 72811961 (GHMatters) P101957.AU GARYC Drawings 5 Figure 1 | 72811961 (GHMatters) P101957.AU GARYC
