| abstract |
This invention relates to a high carbon steel rail with enhanced ductility comprising 0.65 -1.4 mass % of carbon, 0.1-1.5 mass % of silicon-, 0.01-0.4 mass % of manganese, 0.1-1.5 mass- % of chromium, and 0.005-0.05 mass % of titanium, with additional allowances for Mo, Nb,. V, Cu, Ni, Co, B, N, Ca, Mg, Zr, Al, and W, with the remainder comprising iron and the inevitable impurities, that displays a head surface hardness of at least 3.25 HB and & microstructure comprising at least 90% pearlite a depth of between 2-20 mm below the rail head surface. The invention also relates to the- process for manufacturing the high carbon steel rail with enhanced ductility. |
