Product Overview

Q235FTD is a specialized structural steel plate manufactured in accordance with GB/T 28410-2012, specifically designed for wind turbine tower construction requiring enhanced low-temperature toughness. This grade provides optimal strength, excellent weldability, and guaranteed impact properties at -20°C, making it suitable for wind power installations in cold climate regions.

Key Advantages

  • Guaranteed -20°C Impact Toughness: Minimum 47J at -20°C (Grade D), ideal for cold climates.
  • Optimized Weldability: Low carbon (C≤0.18) and controlled alloying elements.
  • Strict Quality Control: Full traceability with EN 10204 3.1/3.2 certification.
  • Versatile Availability: Plates up to 100mm thick, coils available.

Frequently Asked Questions

What is the difference between Q235FTD and Q235FTC?

FTD guarantees impact toughness at -20°C (47J), while FTC guarantees at 0°C. FTD is recommended for colder climates where winter temperatures drop below freezing.

Can Q235FTD be used for offshore wind?

Yes, its -20°C toughness makes it suitable for many offshore applications. For more extreme environments (North Sea, Arctic), consider Q235FTE (-40°C) or Q235FTF (-50°C).

MOQ?

25MT for plates, 50MT for coils. Flexible for trial orders.

Third-party inspection?

SGS, BV, TÜV available upon request.
