50E4 Rail
Product Overview
The 50E4 railway rail is a high-strength heavy rail engineered to meet the rigorous demands of European mainline railways, heavy-haul freight networks, and industrial heavy-duty systems. Compliant with EN 13674-1 and EN 13674-4 standards, this rail is manufactured from advanced pearlitic steel grades (R200, R260, R260Mn, R350HT) to deliver exceptional wear resistance, fatigue strength, and dynamic load capacity.
Key Features
Dimensions:
Weight: 50.46kg/m(111.25 lb)
Head Width: 70 mm | Rail Height: 152 mm | Base Width: 125 mm | Web Thickness: 15 mm
Length: customized from 5m to 25m.
Material & Mechanical Properties
Standards:
EN 13674-1 (rail geometry), EN 13674-4 (dimensions), ISO 9001:2008 (quality management)
Steel Grades:
R200: 200–240 HBW, ≥680 MPa tensile strength; ideal for light-duty regional lines.
R260: 260–300 HBW, ≥880 MPa tensile strength; suitable for mainline freight (axle loads ≤25 tons).
R260Mn: 260–300 HBW, ≥880 MPa tensile strength; enhanced manganese content for abrasive environments (e.g., mining).
R350HT(heat-treated): 350–390 HBW, ≥1175 MPa tensile strength; engineered for ultra-heavy haul (30+ ton axles) and high-speed applications, offering 25% reduced wear compared to non-treated grades.
Customization Services
Rail Processing: Pre-drilled bolt patterns (M24–M30), stress-relieved end machining, and mill-certified weld preparation.
Accessories:
Rail clamps
Fish Plates & bolts for secure 50E4 rail joints.
Rail Pads: 5–15 mm thickness for vibration damping in passenger lines.
Applications
High-Speed Passenger Railways
Deployed in regional express networks where R260’s balanced hardness ensures smooth rides and reduced noise emissions.
Used in feeder lines connecting stations to main TGV/ICE corridors, with R350HT grades supporting higher axle loads from modern EMUs.
Mining & Quarry Systems
Engineered for underground mine railways, resisting deformation from uneven track beds and abrasive ore cart wheels.
R260Mn grade preferred for surface quarry rails, withstanding repetitive loading/unloading of gravel/stone.
Ports & Intermodal Terminals
Critical for container gantry cranes (40+ ton loads), with galvanized 50E4 rails resisting saltwater corrosion and repetitive stress from automated stacking systems.
Used in AGV (automated guided vehicle) rails for seamless integration with warehouse logistics, ensuring precision movement of heavy cargo.
