Frequently Asked Questions

What is the advantage of Q345FTC over lower strength grades?

Q345FTC offers higher minimum yield strength (345 MPa) compared to Q235/275 series, allowing for heavier load designs or material savings while maintaining 0°C impact toughness (47J).

Is Q345FTC suitable for onshore wind in temperate climates?

Yes, its 0°C impact energy (47J) makes it ideal for most onshore wind farms where minimum operating temperatures stay above -20°C. For colder regions consider D, E, or F grades.

MOQ?

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

Third-party inspection?

SGS, BV, TÜV available upon request.
