(57) [Summary] [PROBLEMS] To increase the carbon content of a steel rail and further increase the surface hardness of the rail head, thereby improving the wear resistance of the rail and extending the life of the rail. SOLUTION: At least 0. The average value of the hardness in the range from 05 to 2 mm is Hv5 A rail excellent in wear resistance, characterized in that it is not less than 00. Further, in mass%, C: more than 0.85 to 2.00 %, And cold-worked after hot rolling on the steel rail, at least on the surface of the rail head. |
