RAIL STEEL WITH AN EXCELLENT COMBINATION OF WEAR PROPERTIES AND ROLLING CONTACT FATIGUE RESISTANCE
The invention relates to a high-strength pearlitic steel rail with an excellent combination of wear properties and rolling contact fatigue resistance wherein the steel consists of 0.88% to 0.95% carbon, 0.75% to 0.92% silicon, 0.80% to 0.95% manganese, 0.05% to 0.14% vanadium, up to 0.008% nitrogen, up to 0.030% phosphorus, 0.008 to 0.030% sulphur, at most 2.5 ppm hydrogen, at most 0.10% chromium, at most 0.010% aluminium, at most 20 ppm oxygen, the remainder being iron and un-avoidable impurities.
