Service tests have proved that type R-50 railway rails made of steel containing 0.63 to 0.75% C and 0.7 to 1.0% Mn and alloyed with chromium (0.5 to 1.0%) have an increased (by a mean 25%) resistance to contact-fatigue defects, less wear per 100 million gross tons of freight, and less rippling of the surface after use than carbon steel rails of standard composition. These advantages are obtained if the total C+1/4 Mn content of the steel is not lower than 0.88%.
