Product Introduction
GB heavy rails are the core load-bearing components of railway tracks. They are produced strictly in accordance with GB standards. The main materials are low-alloy steels such as U71Mn and U75V. U71Mn steel, with the solid solution strengthening effect of manganese elements, improves strength while ensuring toughness, and is suitable for railway lines with medium loads; U75V steel forms fine precipitates such as vanadium carbide and vanadium nitride due to vanadium elements, which effectively hinders dislocation movement and increases the fatigue life of the rails by more than 20%, making it more suitable for high-frequency and heavy-load train operations.
GB 38kg Heavy Steel Rail is usually made of U71Mn, with a carbon content of about 0.71% and a manganese content of 1.0 - 1.4%. It has both strength and toughness, a tensile strength of ≥880MPa, a hardness of 280 - 320HB, good wear resistance, and can withstand medium loads;
GNEE RAIL strictly implements national standards in the production of 38KG Steel Rail, and the dimensional accuracy and quality are strictly guaranteed. The rail height of 134mm and the bottom width of 114mm are reasonably designed, which is suitable for light railways or branch lines such as mines, forest areas, and factories, and can meet the use needs of freight lines, factory railways and other scenes;
In addition, the 38kg heavy rail has a simple structure and good weldability. It can be connected by flash welding and other methods, which is convenient for installation and maintenance. At the same time, the manganese element improves the toughness of the material and reduces the risk of brittle fracture. It is stable and reliable under medium-frequency traffic conditions, and is an economical and practical choice for light heavy rails.
