50Mn Heavy Steel Rail Used For Track

43kg heavy rail refers to rail products with a unit length (per meter) weight of 43kg. Its model identification directly uses the nominal linear density (kg/m) as the technical feature code. The geometric parameters of this specification rail include: head width 70mm, vertical height 140mm, bottom plate width 114mm, waist thickness 14.5mm, and the actual unit weight is precisely calculated to be 44.653kg/m. The rail classification system is divided into two categories: heavy rail (≥30kg/m) and light rail (<30kg/m) based on the difference in nominal linear density. Among them, 43kg-grade products are mainly made of high-strength alloy steel materials such as 50Mn and U71Mn.

As an important branch of rail products, the technical definition of heavy rail is based on the nominal linear density threshold (≥30kg/m), which can be specifically divided into conventional railway rails and special equipment rails. Conventional rails (i.e. ordinary rails) are suitable for trunk railways, special lines, curved sections and tunnel projects. The standard length specifications include two basic types of 12.50m and 25.00m. Curved special rails are shortened to form variant specifications such as 12.46m, 12.42m, 24.96m, 50.92m, etc. The current mainstream rail products have formed a standardized linear density sequence of 50kg/m, 60kg/m, 75kg/m, and 100kg/m.
