Product Introduction
75kg/m GB standard heavy-duty rails are important rail components used for heavy-duty railway transportation. The cross-section of the rail is I-shaped and consists of three parts: rail head, rail waist and rail bottom. In order to ensure its load-bearing capacity and bending resistance, the rail head, rail waist and rail bottom of the 75kg/m rail are wider and thicker than other heavy rail specifications to meet the needs of heavy-duty transportation. Through strict production process and quality control, the internal structure of the 75kg/m heavy-duty rail is uniform, with fewer defects, good fatigue resistance, and can withstand long-term alternating loads without fatigue cracks and other damage, which improves the reliability and safety of the track.
Common materials include U71Mn, U75V, U78CrV, etc. These materials have high toughness, wear resistance, fatigue resistance and corrosion resistance by adding different alloy elements, optimizing design and production process, and can withstand the huge load and frequent impact of heavy-load trains.
