Key Advantages

  • Enhanced Yield Strength: 550 MPa minimum up to 40mm thickness – ideal for next‑gen multi‑megawatt turbines.
  • Guaranteed -40°C Impact Toughness: Minimum 47J at -40°C (Grade E) – reliable for arctic and subarctic regions.
  • Superior Purity: Low P (≤0.020) and S (≤0.010) for enhanced low‑temperature performance.
  • Enhanced Alloy Design: Higher Mo, Cr, Ni, Cu limits (Mo≤0.30, Cr≤0.60, Ni≤0.80) for improved strength and hardenability.
  • Optimized Weldability: Low carbon (C≤0.20) and micro‑alloying (Nb, V, Ti) for excellent field welding.

Frequently Asked Questions

What is the advantage of Q460FTE over Q460FTD?

Q460FTE guarantees impact toughness at -40°C (47J) compared to -20°C for Q460FTD, and offers enhanced yield strength of 550 MPa (≤40mm) versus 460 MPa for standard grades. It is designed for arctic conditions with higher strength demand.

Is Q460FTE suitable for the world's largest wind turbines?

Yes, its 550 MPa yield strength and -40°C toughness make it ideal for 15MW+ turbines in cold climates, reducing material thickness and weight while ensuring reliability.

What is the MOQ for Q460FTE 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.
