ISCOR 48 kg Rail (South African ISCOR Standard)
The ISCOR 48 kg rail is the core heavy-duty profile in the South African ISCOR standard series, engineered for high axle load and high-frequency operation scenarios. Manufactured primarily with R260 wear-resistant steel (Grade 900A also available), it features outstanding rigidity, excellent fatigue resistance and long service life. It is the standard specification for regional freight mainlines, heavy mining haulage lines, heavy-load port yards and existing railway upgrading projects, supported by full traceable quality documentation and global export logistics services.

Mechanical Properties
- Tensile strength (R260): ≥ 880 MPa
- Yield strength (R260): ≥ 600 MPa
- Hardness: 260 – 300 HBW
- Elongation (A): ≥ 10%
- Full Mill Test Certificate (MTC) with heat/batch traceability provided per shipment
Core Advantages
- Heavy-haul load capacity: Premium R260 grade delivers exceptional strength and section rigidity, reliably supporting sustained heavy axle loads and dense traffic on mainline and mining routes.
- Superior wear & fatigue resistance: Optimized metallurgical structure and hardness resist surface wear and rolling contact fatigue, extending service life and reducing long-term maintenance costs.
- Factory prefabrication: In-house cut-to-length, precision hole drilling and end preparation reduce on-site machining work and shorten project construction schedules.
- Full quality traceability: Each batch is accompanied by a complete MTC covering chemical composition and mechanical test data. Buyer-appointed third-party inspection and supervised loading services are available on request.
Typical Applications
- Regional freight mainlines and heavy-haul railway sections
- Heavy-load container terminals and port yard tracks
- Mining heavy-haul lines and ore transport corridors
- Reinforcement and capacity upgrading of existing railway lines
- Heavy industrial plant corridors and steelworks internal transport tracks
Quality & Service Support
- Quality assurance: Full-process quality control from raw material inspection through to final dimensional and surface testing, with 100% batch traceability via heat numbers and official MTC documentation.
- Custom fabrication: Precision cutting, drilled holes and end machining manufactured strictly according to client drawings and project specifications.
- Packing & logistics: Bundled on timber skids with rail head protection; rust-proof treatment (oil coating or VCI film) for sea freight; supervised loading service with standardized PDF photo report.
- Technical support: Professional guidance on rail welding, joint installation and routine maintenance to lower overall lifecycle costs.
