Product Introduction

GB high-quality welding performance heavy rail is an important track material used to carry the weight of trains and ensure the smooth operation of trains in railway construction. Common heavy rail specifications are 38kg/m, 43kg/m, 50kg/m, 60kg/m, 75kg/m, etc. Heavy rails of different specifications vary in size. For example, the rail height of 50kg/m heavy rail is 152mm, the bottom width is 132mm, the head width is 70mm, and the waist thickness is 15.5mm.

The main types of railway rails in my country are U71Mn and U75V. Generally speaking, rail materials containing alloy elements such as manganese (Mn) and vanadium (V) have good welding performance and comprehensive mechanical properties. For example, U71Mn rails have high strength and good toughness, and their welding performance is also excellent, which can meet the use requirements of general railway lines.
