What is a heavy rail?

Heavy rails are steel grades that produce rails with a nominal weight greater than or equal to 30kg/m.

The heavy rail has to withstand the pressure, impact load and friction of rolling stock during operation, so it requires sufficient strength, hardness and certain toughness. To meet the needs of railways with heavy loads and high speeds, in addition to increasing the unit weight of heavy rails, it is also necessary to improve overall performance. Higher toughness, wear resistance, crush resistance and brittle fracture resistance are required. The quality requirements of the production process are strict. In addition to ensuring its chemical composition, it also requires inspection of mechanical properties, drop weight test, and acid etching macrostructure inspection.


Main use for:

It is the main component of railway track. Its function is to guide the wheels of rolling stock to move forward, bear the huge pressure of the wheels, and transmit it to the sleepers. The rail must provide a continuous, smooth and drag rolling surface for the wheels. In the electrified railway or automatic block section, the rail can also be used as a track circuit.
