| Property | Parameter | Description |
|---|---|---|
| Product Name | Heavy Rail | Hot-rolled steel rail for railway track construction, also known as heavy steel rail or railroad rail |
| Material Grade | U71Mn / 900A / R260 | Equivalent grades: GB U71Mn, EN 13674 R260, AREMA 136RE, UIC 60 |
| Standard Compliance | GB 2585 / EN 13674 / AREMA / TB/T 2344 | Compliant with Chinese, European, and American railway rail standards |
| Carbon (C) | 0.65% - 0.82% | Primary strengthening element for rail hardness and wear resistance |
| Manganese (Mn) | 0.70% - 1.30% | Enhances tensile strength and hardenability of rail steel |
| Silicon (Si) | 0.15% - 0.58% | Improves strength and deoxidation during steelmaking |
| Phosphorus (P) | ≤ 0.030% | Controlled to minimize cold brittleness |
| Sulfur (S) | ≤ 0.030% | Controlled to prevent hot shortness and improve rail integrity |
| Tensile Strength | ≥ 880 MPa | Per GB 2585 / EN 13674 for R260 grade; ensures load-bearing capacity under heavy axle loads |
| Yield Strength | ≥ 460 MPa | Minimum yield point ensuring resistance to permanent deformation |
| Elongation | ≥ 10% | Measured on gauge length of 50 mm per applicable standard |
| Rail Profiles | 43 kg/m, 50 kg/m, 60 kg/m, 75 kg/m | Common profiles include 50N, UIC60, 136RE; weight per meter ≥ 38 kg/m classified as heavy rail |
| Rail Length | 12.5 m / 25 m / 50 m / 100 m | Standard and long-welded rail lengths available; custom lengths upon request |
| Surface Finish | Hot-rolled / Head-hardened | Optional online or offline head hardening for enhanced wear and rolling contact fatigue resistance |
| Application | Mainline railway, high-speed rail, heavy haul freight, metro transit, crane rail | Suitable for axle loads from 25 t to 40 t in passenger and freight operations |
| Certification | ISO 9001 / CE / IRIS / CRCC | Third-party inspection available: SGS, BV, Lloyd's |
| Packaging | Bundled in stacks, secured with steel straps | Rust-preventive oil coating optional; marked with grade, length, and heat number |
| MOQ | 30 Metric Tons | Smaller quantities negotiable based on profile and grade availability |
Delivery Delay Resolved, Product Quality Was Fine
We ordered 900 tons of 136RE rail for a crane runway installation at Jebel Ali port facility. The rail quality itself was good — hardness tested at 305-315 HB on the head, chemical composition matched the AREMA cert, and dimensional accuracy was within tolerance. However, the initial shipment was delayed by about three weeks beyond the confirmed delivery date due to a production scheduling issue. To their credit, the supplier was transparent about the delay, provided regular updates, and offered a discount on our follow-up order as compensation. The issue was resolved professionally and we'd consider ordering again with a longer lead time buffer.
