Abstract: PURPOSE:To produce the rail which is easy to weld and forms the zeld zone in which the material characteristics, such as strength and structure of the weld zone, have not much difference from those of base metals, by making the cooling conditions equivalent to the rate of cooling at the rail welding at the time of heat-treating the top part of the rail made of high carbon low alloy steel. CONSTITUTION:The rail is produced by the high carbon low alloy steel which contains C; 0.55-0.85%, Si; 0.50-1.20%, Mn; 0.80-1.50%, Al; 0.005-0.05% or further contains Cr; 0.20-0.90%, Nb; 0.004-0.010% and contains these so that the total amount of Cr+Mn becomes 1.60% or less. The top surface layer of this rail is heated to 850 deg.C or more to austenitize its structure, after which it is quenched at 50-400 seconds between 800 deg.C and 550 deg.C. The structure becomes fine pearlite from the rail top surface layer down to a depth of 10mm and the rail of the superior weldability whose tensile strength at ordinary temperature is 120kg/mm<2> or more and surface hardness HB330 or more may be produced.
