Key Advantages

  • Ultra‑High Strength + Cold Toughness: Minimum yield 460 MPa (≤16mm) with guaranteed 47J at -20°C (Grade D) – ideal for cold climates.
  • Enhanced Alloy Design: Higher Mo, Cr, Ni, Cu limits (Mo≤0.30, Cr≤0.60, Ni≤0.80) for improved strength and low‑temperature performance.
  • Optimized Weldability: Low carbon (C≤0.20) and micro‑alloying (Nb, V, Ti) for excellent field welding.
  • Strict Quality Control: Full traceability with EN 10204 3.1/3.2 certification.
  • Versatile Availability: Plates up to 100mm thick, wider/longer dimensions on request.

Frequently Asked Questions

What is the advantage of Q460FTD over Q460FTC?

Q460FTD guarantees impact toughness at -20°C (47J) compared to 0°C for Q460FTC, making it suitable for cold regions while maintaining the same 460 MPa yield strength.

Is Q460FTD suitable for offshore wind in cold seas?

Yes, -20°C impact meets requirements for many North Sea, Baltic, and cold offshore projects. For arctic offshore, consider Q460FTE or Q460FTF.

What is the MOQ for Q460FTD plates?

25MT for plates, 50MT for coils. Trial orders (10-15MT) may be accepted after discussion.

Third-party inspection available?

SGS, BV, TÜV inspection can be arranged at extra cost; mill certificate EN 10204 3.1 is always included.
