This paper reviews the cutting-edge advances in high-strength steel plates for wind turbine towers and high-grade non-oriented silicon steel for electric vehicles (EVs). China’s cumulative installed wind power capacity has reached 650 GW, accounting for 16.5% of the country’s total installed power generation capacity. Driven by the booming demand for wind power development, wind turbines are trending toward larger-scale designs, with tower heights increased up to 200 meters and a maximum yield strength of 500 MPa. For both onshore and offshore applications, as strength grades are upgraded, the fatigue performance of welded joints must be simultaneously improved, making the optimization of welded joint performance particularly critical.
In the electric vehicle sector, China’s EV ownership has reached 43.97 million, accounting for 12.01% of the total vehicle stock. EV production is projected to reach 16.626 million units in 2025.
A single EV consumes 45–60 kg of silicon steel, driving an annual demand of 650,000 to 700,000 tons. To meet these stringent performance requirements, establishing the process-microstructure-property relationship through industrial big data and microstructural digitization, and further developing big data-driven AI prediction models, has become a key research direction for stabilizing material performance and reducing manufacturing costs. |
