What is JIS steel grade equivalent to?

Jan 20, 2026 Leave a message

Rail track is an essential component of rail track, and its function is to guide the train wheels moving forward by withstanding the enormous pressure pushed by the wheels. Steel rail shall provide smooth, stable and continuous rolling surface for the passing train wheels. In electrical railway or automatic block section, railway track can also be used as track circuit.

As a professional rail fastener supplier, GNEE RAILWAY RAILWAY can provide different standard steel rail such as GB,American, BS, UIC, DIN, JIS, Australian and South Africa which used in railway lines, cranes and coal mining.

 

Common Rail Steel Grades Worldwide:

 

Grade Standard / Region Typical Composition (wt%) Key Features & Applications
R260 EN 13674-1 (Europe) C: 0.67–0.80, Mn: 0.90–1.20, Si: ≤0.50 Base-grade rail; cold-rolled; widely used on medium-traffic lines. Good weldability and cost efficiency.
R350HT EN 13674-1 (Europe) C: 0.75–0.85, Mn: 0.80–1.20, Cr: 0.20–0.50 Heat-treated (online/offline); UTS ≥1100 MPa; 30–50% longer life than R260. Standard for high-speed (TGV, ICE) and heavy-haul lines.
Grade 260 AREMA (North America) C: ~0.77, Mn: ~1.0–1.2, Si: ~0.2 Equivalent to R260; used with rail sections like 115RE, 136RE. Common on Class I freight networks.
Grade 350 AREMA + Mill Specs (USA/Canada) C: 0.78–0.83, Mn: 0.90–1.20, Cr: 0.2–0.6, + V/Nb (microalloyed) TMCP or heat-treated; UTS ~1180–1280 MPa. For demanding curves, heavy axle loads (>33 ton), and high-tonnage corridors.
BH Rail (Bainitic) JIS E 1101 (Japan), adopted in EU/India C: 0.65–0.80, Mn: 1.0–1.4, Cr/Mo/Ni (optional, mill-specific) Bainitic microstructure; high strength (UTS ~1250–1350 MPa) + superior fracture toughness. Used on Shinkansen curves and high-wear segments.
U71Mn GB/T 2585 (China) C: 0.65–0.77, Mn: 1.10–1.40, Si: 0.15–0.35 Work-hardening carbon-manganese rail; standard for 50kg/m, 60kg/m rails on Chinese mainlines. Comparable to R260/R350 in performance.
U75V GB/T 2585 (China) C: 0.67–0.77, Mn: 0.70–1.00, V: 0.04–0.12 Vanadium-microalloyed; higher strength & fatigue resistance than U71Mn. For high-speed (e.g., Beijing–Shanghai HSR) and heavy-haul lines.

 

What is JIS steel grade equivalent to?

 

JIS steel grades, defined by Japanese Industrial Standards (JIS), are often equivalent in chemical composition and mechanical properties to grades in GB (China), EN/DIN (Europe), ASTM (USA), and BS (UK) standards, but they are not always 100% identical.

 

What is JIS steel equivalent to in other standards?

 

JIS grades are commonly matched with:

 

  • GB (China National Standard)
  • EN / DIN (European Standard / German Standard)
  • ASTM / AISI (American standards)
  • BS (British Standard)

 

track rail

 

For steel rails, equivalence focuses on hardness, wear resistance, and fatigue performance, not just chemistry.

 

Typical equivalence relationships:

 

JIS Rail Grade GB Rail Grade EN/UIC Grade Application
JIS 50N GB 50kg/m UIC 50 Light mainline / metro
JIS 60 GB 60kg/m UIC 60 (R260/R350HT) Heavy haul / high speed
JIS 30kg GB 30kg/m DIN S30 Industrial / mining
JIS 22kg GB 22kg/m DIN S20 (similar use) Mining / light transport

 

Although weights may match, section profiles and tolerances can differ, so rails are not always interchangeable without checking drawings and fastening systems.

 

GNEE RAILWAY RAILWAY routinely supplies GB, JIS, EN/UIC, BS, DIN, and AREMA steel rails, and can verify profile compatibility, chemical composition, and mechanical performance before replacement or mixed-standard installation.
