60kg Rail | GB 60kg Steel Heavy Rail
GB 60kg rail，with a unit weight of 60.64kg/m. It is made of high-carbon manganese steel (50Mn/U71Mn), featuring both high strength and anti-fatigue properties.
It is specially designed for scenarios subject to dynamic load impact of locomotives and high-frequency rolling, and is applicable to national railway trunk lines, subways and industrial transportation lines.
Product Introduction
The GB 60kg steel rail is a standard type of heavy-duty rail widely used in railway and industrial transportation systems. Manufactured from high-strength carbon–manganese alloy steel, it possesses excellent bending resistance, shear strength, and wear resistance. This rail type is primarily applied in heavy-haul railways, mining tracks, port loading lines, and crane operating tracks. Its cross-sectional design complies with China's national standard GB 2585-2007, ensuring that the rail maintains excellent geometric stability and operational reliability under continuous heavy loads and dynamic impact conditions.
Product Specifications
The theoretical unit weight of the 60kg rail is 60.64 kg/m, with a rail height of 176 mm, head width of 73 mm, base width of 150 mm, and web thickness of 16.5 mm. It is produced using standard U71Mn or U75V steel, and the hot rolling and controlled cooling processes ensure uniform microstructure and fine grain quality. The rail surface undergoes flaw detection and ultrasonic inspection to prevent cracks or inclusions that could affect service life.
| Steel Grade | C(%) | Si | Mn | Cr | V | P | S | Tensile Strength (Rm/MPa) |
| U71Mn | 0.65~0.76 | 0.15~0.58 | 0.70~1.40 | – | – | ≤0.035 | ≤0.030 | ≥880 |
| U75V | 0.71~0.80 | 0.50~0.80 | 0.75~1.05 | – | 0.04~0.12 | ≤0.035 | ≤0.030 | ≥980 |
U71Mn steel is renowned for its excellent impact toughness, enabling it to withstand high wheel pressure and alternating stresses. Its uniform surface hardness distribution effectively reduces rolling wear and metal fatigue. The wide-base design of the rail foot increases the load-bearing area on the sleepers, enhancing the overall stability of the track system. Meanwhile, the precision-polished rail head ensures smooth wheel-to-rail contact, minimizing noise and vibration during operation.
GB 60KG Rail Performance Advantages
High Strength and Low Deformation: Suitable for environments with frequent braking and heavy-load operations
.
Excellent Wear Resistance: The wear life of the rail head is more than 40% longer than that of ordinary carbon steel rails.
Strong Stability: The wide-base design distributes the load on the sleepers more evenly, preventing foundation settlement.
Wide Adaptability: Maintains reliable performance under high temperature, humidity, salt fog, and dusty conditions.
