FAQ

❓ How are Chinese wind turbine steel plates classified?

They are classified mainly by yield strength (Q235–Q690) and low-temperature toughness (B–F). FT indicates the steel is for wind turbine use, not temperature.

❓ What do B, C, D, E, F mean in steel grades?

These letters indicate low-temperature impact toughness levels, with higher letters representing better performance in cold environments. For example, F > E > D > C > B.

❓ What does FT stand for in wind turbine steel grades?

FT = “for wind turbine”, indicating that the steel is specifically manufactured for wind turbine towers and structural components.
