Used Rails - Technical Analysis

Used Rails R50 - R65: High-Carbon Scrap for Re-Rolling & Melting

Industrial used rails represent the highest tier of ferrous scrap. Due to their rigorous manufacturing standards (GOST/ASTM), they offer a unique chemical profile—high carbon and low phosphorus—making them the ideal feedstock for Re-Rolling Mills and Electric Arc Furnaces (EAF).

1. R50 vs. R65 GOST Classification

The grade designations refer to the linear mass of the rail, indicating its density and cross-sectional area.

  • R50 (51.67 kg/m): Typically sourced from standard transport lines. Preferred for re-rolling into angles, flats, and smaller construction bars.

  • R65 (64.72 kg/m): Heavy-duty rail used for high-capacity freight lines. Prized for melting due to its superior mass-to-surface ratio, minimizing oxidation losses.

2. Why Rails? The "Clean" Scrap Advantage

Unlike HMS, railway scrap is structurally uniform and chemically predictable.

  • Re-Rolling Advantage: Many mills "re-roll" used rails directly into secondary construction profiles without re-melting, offering massive energy savings.

  • Chemical Purity: Rails are free from "hidden" contaminants like plastics, copper windings, or rubber found in machine scrap.

3. Logistics: Cut Rails and ISRI Compliance

Handling heavy steel requires specialized equipment.

  • Cut Specifications: Standard industry demand is for 1.2m or 1.5m cut rails to facilitate charging into furnaces.

  • ISRI Standards: We guarantee compliance with ISRI 27 - 29 specifications for all bulk shipments.

Frequently Asked Questions

What are used rails (R50/R65) and what markets buy them?

Used rails are reclaimed railway tracks, classified by weight per meter: R50 (50 kg/m) and R65 (65 kg/m). They are purchased by steel mills for re-rolling into new products, or by infrastructure projects in developing markets for direct reuse. India, Bangladesh, Pakistan, and Southeast Asia are the primary buyers.

What is the standard inspection process for used rails?

Inspection covers: rail profile (head wear measurement), length compliance (typically 12–25m), absence of cracks or breaks, and contamination check. SGS or Bureau Veritas inspection at loading port issues a Certificate of Quality. Buyers often specify maximum head wear in mm.

What are typical Incoterms and payment terms for used rail transactions?

CFR (Cost and Freight) to destination port is the most common term. Payment is typically 100% irrevocable LC for first transactions, or 30% advance + 70% against BL for established buyers. Minimum order quantities are typically 1,000–5,000 MT per shipment.

How are used rails priced relative to HMS scrap?

Used rails typically trade at a premium to HMS 1&2 scrap due to their higher metallic yield and lower processing cost for re-rollers. The premium varies by market but is typically $20–50/MT above HMS CFR Turkey equivalent. Rail quality (wear level, origin) significantly affects the premium.
