Abstract

Abstract

The high carbon low manganese hot rolled steel rail is subject to heat treatment,using double frequency induction heating and slack quenching with compressed air. The PD₂75kg/m heat treated rail was developed which is characterized by fine pearlitic structure;a depth of hardened layer ≥ 15mm and mechanical property:σ_0.22815~980MPa, σ_b1185~1340MPa, δ₅10%~15%, room temperature impact toughness aK 14~33J/cm², average fracture toughness K_Ic 45.5MPa·m^1/2. The newly developed rail has a fair combined property of high strength,good ductility and toughness,and excellent service performance with its service life over twice that of the U71Mn hot rolled rail.
