What metal is commonly used for train rails?
Jan 19, 2026
Steel rail, we also called the railway track, it is crucial to the steel railing system. As a rail component of the railway system, steel rail guides the train forward and bears the enormous pressure. Meanwhile, the steel rails convey the pressure to the railway sleepers. So steel rails play a big role in the railway system and the quality of the steel rails is much important.
Besides, steel rails have another crucial function. The steel rails provide a smooth and less resistance surface for the vehicles that ensure the safe running.
What metal is commonly used for train rails?
Steel rails, the essential components of railway tracks, are primarily made from high-strength carbon-manganese steel. This material is chosen for its excellent combination of hardness, wear resistance, and toughness, allowing rails to withstand the enormous pressure and dynamic loads from trains. Typical grades include U71Mn, U75V, 55Q, Q235, and R350HT, which are widely used in industrial, mining, and mainline railway applications.
| Steel Grade | Carbon (%) | Manganese (%) | Silicon (%) | Typical Use |
|---|---|---|---|---|
| U71Mn | 0.65–0.76 | 1.10–1.40 | 0.15–0.35 | Mainline heavy rail, high-speed rail |
| U75V | 0.71–0.80 | 0.70–1.05 | 0.50–0.80 | High-speed rail, heavy-duty applications |
| 55Q | 0.50–0.60 | 0.60–0.90 | 0.15–0.35 | Light rail, industrial lines |
| Q235 | 0.12–0.20 | 0.30–0.70 | ≤0.30 | Mining rail, light industrial lines |
| R350HT | 0.70–0.82 | 0.60–1.25 | 0.13–0.60 | High-speed European mainlines |
Steel is used over other metals such as iron or aluminum because it provides a perfect balance of strength, durability, and resistance to wear and fatigue. Unlike pure iron, steel rails can endure repeated dynamic loads from high-speed or heavy freight trains without deforming. Carbon-manganese steels like U71Mn are heat-treated to further improve hardness, allowing longer service life and minimal maintenance. In addition, steel's uniform properties ensure smooth rolling surfaces, which reduces wheel wear and improves safety.
How Are Steel Rails Produced?
Rails are manufactured through hot-rolling processes, where carbon-manganese steel is heated and shaped into an I-shaped cross section, consisting of the rail head, web, and foot. This design ensures maximum bending resistance and load distribution. Some rails undergo heat treatment to enhance wear resistance, especially for high-speed or heavy-duty tracks. GNEE RAIL produces both standard rails and custom rails to meet various international standards, including GB, UIC, JIS, AREMA, and DIN, ensuring compatibility for global rail systems.
| Standard | Rail Type | Weight (kg/m) | Length (m) | Material |
|---|---|---|---|---|
| GB11264-89 | Light Rail 22KG | 22 | 6–12 | Q235, 55Q |
| UIC860 | UIC60 | 60.21 | 12–25 | R260, R350HT |
| JIS E1101 | 22KG | 22.3 | 9–12 | JIS E Steel |
| AREMA | 60RE | 60 | 12–25 | SS, HH, LA, IH |
| DIN 536 | A100 | 100 | 10–12 | 900A |
