Nanjing Steel is an industry-leading, highly efficient and fully integrated steel complex with annual production capacity of over 10 million tonnes, primarily producing specialised plates and long steel products. R&D focuses on steel materials exhibiting high strength, high toughness, high fatigue resistance, high wear resistance, corrosion resistance and excellent weldability, widely used in oil and gas equipment, renewable energy, shipbuilding and marine engineering, automotive bearings and springs, construction machinery, rail transport and high-rise bridge structures.
Core advanced steel materials sales reached 2.827 million tonnes in 2025 (+8.09% YoY), accounting for 30.5% of total steel sales (+2.42pp YoY). Gross margin: 20.88% (+3.71pp YoY). Gross profit contribution: 48.15% of total steel products.
Embracing AI to foster new quality productive forces. In partnership with Huawei, Nanjing Steel launched “YuanYe,” the steel industry’s first dedicated LLM architecture, spanning four core interfaces—raw materials to ironmaking, ironmaking to steelmaking, steelmaking to rolling and customer service—and supporting R&D, production, marketing and operations. It rolled out 20 AI pilot applications, driving data integration and intelligent upgrading across the full process and value chain. Digitalisation across all businesses reached 85%, while key equipment digitalisation and the numerical control rate of key processes both reached 100%; the new-product R&D cycle was cut by 50%. Aligned with the national “Data Element ×” and “AI+” strategies, Nanjing Steel built a data management system for large steel enterprises, integrated over 95% of core data assets into its data lake, developed the proprietary “Data-to-Gold” platform and achieved RMB23.24 million in data asset capitalisation. It was designated as China’s inaugural pioneer-level smart factory and was the only steel company selected for the national pilot programmes on National Data Infrastructure investment and the Innovative Development of Trusted Data Spaces.
Won 15 provincial/ministerial awards, including five Jiangsu Science and Technology Progress Awards and six metallurgical science and technology awards. Formulated or revised 20 international, national and industry standards, including one international standard.
Steady advancement of the overseas layout. Nanjing Steel’s first overseas project—a coke production base in Indonesia with annual capacity of 6.5 million tonnes—now has all ten ovens in operation, delivering coke sales of 3.83 million tonnes in 2025 (+33% YoY). Steel products were sold to more than 40 countries and regions, with annual exports reaching 1.63 million tonnes (+9% YoY).
