Frequently Asked Questions

What is the main difference between Q420FTE and Q420FTD?

Q420FTE guarantees impact toughness at -40°C (34J) compared to -20°C (47J) for Q420FTD. It also has stricter P≤0.020 and S≤0.010, making it suitable for arctic and subarctic environments.

Is Q420FTE suitable for offshore wind in freezing seas?

Yes, its -40°C impact meets requirements for Arctic offshore projects, e.g., in the Barents Sea or northern Baltic. For extreme conditions below -40°C, consider Q420FTF.

What is the MOQ for Q420FTE 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.
