Frequently Asked Questions

What is the advantage of Q345FTD over Q345FTC?

Q345FTD offers guaranteed -20°C impact toughness (47J) compared to 0°C for Q345FTC, making it suitable for colder climates while maintaining the same 345MPa yield strength.

Is Q345FTD suitable for onshore wind in cold regions?

Yes, its guaranteed -20°C impact energy (47J) makes it ideal for onshore wind farms in cold temperate zones where winter temperatures can drop to -20°C.

MOQ?

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

Third-party inspection?

SGS, BV, TÜV available upon request.
