Grain-oriented electrical steel (GOES)
BOTTLENECKData-center power supplies require a GOES grade that lacks substitutes at scale, and Nippon Steel controls much of the global capacity.
High-silicon steel sheet engineered for low core loss and high magnetic permeability in transformer cores. Grid transformers and data-centre power supplies require this specific grade; no substitutes exist at scale. Nippon Steel, JFE, Thyssenkrupp, Baowu, and NLMK control most global capacity, exercising pricing power.
What the evidence shows
High Permeability GOES held 57.78% share of the grain oriented electrical steel market in 2024.
mordorintelligence.comThere is a limited number of domestic manufacturers capable of producing high-grade GOES as of 2024.
