A steel alloy, particularly adapted for the manufacture of railway wheels is provided. Such alloy comprises essentially, in weight percentage, carbon 0,67 - 0.77, manganese 0.70-0.85, silicon 0,65 - 0.85, phosphorus less than 0.025, sulfur less than 0.025, chromium 0.18 - 0.25, molybdenum 0.08 - 0.12, with the balance essentially iron. Another lower carbon alloy comprises essentially, in weight percentage, carbon 0.16-0.45, manganese 0.90-1.10, silicon 0.50-0.70, phosphorous less than 0.035, sulfur less than 0.035, nickel 1.0-1.5, chromium 0.40-0.60 and molybdenum 0.40-0.60. |
