High-strength bainitic steel rails have improved resistances to surface fatigue failures and wear required of the head of rails for heavy-load service railroads. The high-strength bainitic steels rails having excellent resistances to surface fatigue failures and wear contain constituents of specific ranges and consisting of bainitic structures at least in part are characterized in that the total area occupied by carbides whose longer axes are 100 to 1000 nm in a given cross section of said bainitic structures accounts for 10 to 50 percent thereof.
Rail en acier de type bainite à haute résistance qui présente une résistance améliorée aux dommages de fatigue en surface et une résistance améliorée à l'usure au niveau d'une partie tête du rail, exigées pour un chemin de fer à charges lourdes. Ledit rail contient des constituants spécifiques et présente une structure bainitique sur une de ses parties, caractérisée en ce que la somme des surfaces occupées par des carbures ayant des diamètres principaux dans la plage de 100 à 1.000 nm en une section transversale arbitraire de la structure bainitique représente 10 à 50 % de la surface de ladite section transversale arbi
