Abstract

A high-strength, damage-resistant rail characterized by essentially consists of 0.60 to 0.85 wt% of C, 0.1 to 1.0 wt% of Si, 0.5 to 1.5 wt% of Mn, not more than 0.035 wt% of P, not more than 0.040 wt% of S, and not more than 0.05 wt% of A l , a balance being Fe and indispensable impurity. The rail comprises corner and head side portions (2, 3) having a Brinell hardness HB of 341 to 405 and a head top portion (1) having a hardness which is not more than 0.9 of the Brinell hardness of the corner and head side portions. <IMAGE>
