Market Segments Insights:

By Flange Type: The Tower Flanges Segment Dominated the Global Forged Wind Turbine Flanges Market

The global forged wind turbine flanges market is bifurcated into flange type, material, manufacturing process, turbine capacity, application, and geography. On the basis of flange type, the tower flanges segment dominated the global market because they provide critical structural connections between tower sections and withstand substantial bending, compression, and fatigue loads during turbine operation. The increasing scale of modern wind turbines is raising demand for large-diameter forged tower flanges with high strength, dimensional accuracy, and long-term durability.

The demand for larger and more precisely machined tower flanges is increasing as turbine structures expand in size. In 2025, CNC Onsite began machining 97 bottom tower flanges for Vestas’ 15 MW V236 turbines, with the flanges reaching 7.5 meters in diameter; the machining process achieved improved flatness beyond the specified tolerance. This development highlights the growing importance of precision manufacturing for large forged tower flanges used in high-capacity turbines.

By Material: The Carbon Steel Sub-category Holds the Largest Share of the Global Forged Wind Turbine Flanges Market

On the basis of material, the global forged wind turbine flanges market is further segmented into carbon steel, alloy steel, stainless steel, and others. The carbon steel sub-category dominated the global market because of its strong balance of mechanical strength, toughness, weldability, machinability, availability, and cost efficiency. Wind turbine towers commonly use structural steel grades such as S355, while tower flanges are generally forged and rolled from S355-grade steel, making carbon and low-alloy structural steels well established across turbine tower construction.

The segment also benefits from the large installed base of steel tower structures and continued deployment of onshore wind turbines, where economical and durable materials remain important for project economics. S355 steel provides the strength and ductility required for fatigue-loaded flange connections, while its established manufacturing and processing infrastructure supports consistent availability. Recent research on wind turbine flange connections continues to evaluate S355 structural steel because of its ductile behavior under cyclic loading, supporting its relevance for fatigue-critical turbine structures.
