Patent ID: 8469284

Claim:
A pearlitic rail comprising a steel consisting of: in terms of percent by mass, C: 0.65% to 1.20%; Si: 0.05% to 2.00%; Mn: 0.05% to 2.00%; and REM: 0.0005% to 0.0500%, with the balance being Fe and inevitable impurities, wherein, in 95% or more of a metallographic structure contained in a head surface portion which ranges from surfaces of head corner portions and a head top portion to a depth of 10 mm in a head portion of the rail or in a portion which ranges from the surfaces of the head corner portions and the head top portion to a depth of 20 mm in the head portion is a pearlite structure, the hardness Hv of the head surface portion is in a range of 320 to 500, and an average value of ratios (L/D) of long side lengths (L) to short side lengths (D) of Mn sulfide-based inclusions observed in an arbitrary cross-section taken from a portion ranging from the surface of the head top portion to a depth of 3 mm to 10 mm along a longitudinal direction of the pearlite structure is in a range of 5.0 or lower.
