60kg Rail Material Grade
GB 60kg rail (60kg/m) primarily uses U71Mn and U75V steel grades, complying with the GB 2585-2007 standard for heavy rails. These rails are widely used in Chinese railways and urban transit, with U75V often utilized for high-speed lines and U71Mn for general heavy-haul or crane applications, providing high wear resistance and strength.
Key Material Grades (GB Standard):
- U75V: Core material for high-speed, high-strength rails (350km/h), designed for enhanced wear resistance, often employing online quenching technology (QST) to increase tensile strength to ≥980MPa.
| Steel Grade | C(%) | Si | Mn | Cr | V | P | S | Tensile Strength (Rm/MPa) |
| U75V | 0.71~0.80 | 0.50~0.80 | 0.75~1.05 | – | 0.04~0.12 | ≤0.035 | ≤0.030 | ≥980 |
- U71Mn: Commonly used for heavy-duty railways, special railway lines, and crane hoisting equipment, offering robust wear resistance, especially in curved tracks.

Performance Advantages of GB 60kg Rail
GB 60kg rail (standard GB2585-2021) is a high-performance steel rail designed for heavy-haul, high-traffic, and high-speed railways. Offering a weight of 60.64kg/m and often made from durable U71Mn steel, it delivers superior wear resistance, high strength-to-weight ratio, reduced maintenance costs, and exceptional fatigue resistance for modern railway infrastructure.
Key Performance Advantages:
- Exceptional Wear and Fatigue Resistance: Primarily made of U71Mn alloy steel, 60kg rails offer high hardness and tensile strength (≥ 880MPa), making them ideal for high-load environments and reducing the impact of heavy loads on the rail surface.
- High Load-Bearing Capacity: Engineered for heavy locomotives and high-density freight, the 60kg rail is designed specifically for mainlines and heavy-haul traffic, ensuring stability and safety.
- Reduced Maintenance Costs: The superior durability of the 60kg rail reduces the frequency of rail replacement and maintenance, which is crucial for high-speed and busy freight routes.
- Enhanced Stability at High Speeds: The increased rail height (approx. 176mm), thicker web (16.5mm), and overall increased rigidity (compared to lighter rails) offer better vertical stiffness, essential for passenger comfort and safe operation at high speeds.
- Superior Service Life (Bainite Rails): Special 60kg bainite rails can last over 48 months in heavy-haul environments, offering double the service life of standard pearlitic rails.
- Superior Performance in Harsh Conditions: These rails excel in mining environments, industrial setups, and port container terminals, where they endure heavy, repetitive loads and resist deformation and corrosion.
What is the difference between GB 60KG Rail and UIC60 Rail?
GB 60KG rail (Chinese standard GB/T 2585-2007) and UIC60 rail (European standard 60E1/EN 13674-1) are both ~60 kg/m heavy-duty rails for high-speed and freight lines, but they differ in profile dimensions (height, width, head width), steel grades, and manufacturing standards, with UIC60 specifically designed for international compatibility.
Key Differences:
Profile and Dimensions:
- UIC60 (60E1): Measures 172mm in height, 150mm in base width, and 74.3mm in head width.
| Type of Rail | Standard | Dimensions (mm) | Section S | Mass m | ||||
| H | B | C | D | E | cm² | kg/m | ||
| European standard EN 13674-1 | ||||||||
| 60E1 (UIC60) | EN 13674 - 1 | 172,00 | 150,00 | 72,00 | 51,00 | 16,50 | 76,70 | 60,21 |
- GB 60KG: Traditionally has a height of 176mm and a base width of 150mm. The GB standard focuses on localized optimization for high-load, high-speed lines in China.
Standards and Application:
- UIC60: Follows European standards, designed for international high-speed, heavy freight, and urban transit.
- GB 60KG: Complies with Chinese National Standards (GB/T), heavily utilized for high-speed railways and heavy-haul freight within China.
Weight:
- UIC60: Usually listed at 60.21 kg/m.
- GB 60KG: Similar weight, often labeled as 60.64 kg/m or 60.8 kg/m depending on the exact specification.
Material: Both commonly use high-quality carbon-manganese steel, but the chemical composition tolerances may differ based on EN 13674 vs. GB/T standards.
While sometimes used interchangeably, their differing dimensions mean they are not directly compatible in the same track section.
