摘要
The purpose of the present invention is to provide a pearlite rail that has little softening in a welding heat affected zone, high hardness, and high ductility, a flash butt welding method for a pearlite rail, and a method for manufacturing a pearlite rail. In mass percentage, the pearlite rail contains 0.70 - 1.0% C, 0.1 - 1.5% Si, 0.01 - 1.5% Mn, 0.001 - 0.035% P, 0.0005 - 0.030% S, and 0.1 - 2.0% Cr, with the remainder being Fe and inevitable impurities, and the γ + θ temperature range is 100°C or less.
