Product Introduction
GB heavy rails are heavy rail steels for railways produced in accordance with national mandatory standards. Their production process integrates modern metallurgical technology and precision processing technology. Electric arc furnaces or converters are used in the steelmaking stage, combined with LF furnace refining and VD furnace vacuum degassing processes to produce high-quality molten steel; after the molten steel is cast into billets by a continuous casting machine, it enters the hot rolling production line and is gradually formed through multiple rolling passes. In order to improve the overall performance, heat treatment processes such as online normalization and offline quenching are used to adjust the organizational structure and mechanical properties of the steel.
P75 75KG GB standard freight heavy rail is a heavy rail commonly used in railway freight. It is usually made of materials such as U71Mn and U75V. Taking U75V as an example, it is a vanadium-containing micro-alloy rail material. The addition of vanadium can improve the strength, toughness and wear resistance of the rail, enabling it to withstand the heavy axle weight and frequent loads of freight trains.

Product Application
P75 75KG GB freight heavy rail is mainly used in heavy-duty railway freight lines, such as Daqin Railway and other special coal transportation lines, and other railway trunk lines that undertake large-scale freight transportation tasks. These lines usually run heavy-duty and high-density freight trains, and have extremely high requirements for the bearing capacity and wear resistance of the rails. P75 75KG GB freight heavy rail can adapt well to such working conditions and ensure the safety and efficiency of railway transportation.
GNEE RAILWAY RAILWAY is a core supplier of GB standard heavy rail products, committed to providing high-quality materials for global railway infrastructure construction. We have established a strict quality traceability system, implementing full-process quality control from raw materials entering the factory to finished products leaving the warehouse, and equipped with a professional international trade service team, which can provide customers with multi-language business support, technical consultation and after-sales guarantee services.
