Effect of Isothermal Bainitic Quenching on Rail Steel Impact Strength and Wear Resistance

  • HEAT TREATMENT
  • Published:
Metal Science and Heat Treatment Aims and scope

The effect of heat treatment regimes on hardness, impact strength, and wear resistance of rail steel for high-speed tracks (rail quality category R350HT) is studied. Analysis of steel properties with a different structure is compared: pearlitic, and upper and lower bainite. It is shown that the steel with bainitic structure has the best impact strength, but wear resistance is better for steel with a lower bainite structure.
