In the railway transportation system, U71Mn 60kg GB heavy rail is the core component to ensure safe and efficient transportation. "U71Mn" means that it is a manganese-containing high-carbon steel with a carbon content of about 0.71%. Manganese enhances strength and toughness; "60kg" refers to the weight per meter, which has a strong carrying capacity; "GB" represents compliance with national standards to ensure stable quality.

60KG GB Heavy Rail has three core advantages: high strength and high toughness enable it to withstand the impact of heavy train loads and is not easy to break at low temperatures; the rail head has been specially treated with high hardness and excellent wear resistance, which effectively extends the service life and reduces maintenance costs; good welding performance ensures the quality of rail connection and ensures the integrity of the line.
From a production perspective, 60KG Heavy Steel undergoes multiple processes such as steelmaking, continuous casting, rolling and finishing. Steelmaking strictly controls the composition, continuous casting ensures the quality of ingots, and rolling and finishing ensure dimensional accuracy and surface quality.
In terms of application, U71Mn 60kg GB heavy rail is suitable for multiple scenarios: high-speed and stable operation on high-speed railways; carrying bulk cargo transportation on heavy-duty railways; and meeting high-frequency passenger transportation needs in urban rail transit.
