The stainless steel industry will burst with renewed vitality amid transformation in 2025: leading enterprises are clustering to deploy green intelligent production lines, domestic production of high-end materials continues to achieve breakthroughs, while accelerating global expansion under export pressures. The dual trends of heightened industrial concentration and elevated technological barriers are becoming increasingly pronounced, with the industry ecosystem undergoing profound restructuring.Capacity deployment exhibits ‘green clustering’ characteristics, with benchmark projects progressively materialising. In April, Hangzhou Iron & Steel and Zhen Shi Holdings commenced construction on the Dongfang Special Steel Green High-End Nickel-Chromium New Materials Project in Jiaxing, with a total investment of RMB 16.29 billion. Upon completion, it will establish a production capacity of 2.51 million tonnes of stainless steel plates/coils. Highlighted by ‘fully green electricity production,’ this initiative aims to create a zero-carbon smart factory. Its products target high-end sectors such as new energy vehicles and shipbuilding, directly addressing the domestic substitution of alloy materials. Concurrently, the industrial cluster in Ningde, Fujian continues to expand, with projected output reaching 13.2 million tonnes by 2025 – a 6.5% year-on-year increase. Together with Foshan and Wuxi, it forms the core production belt spanning East and South China, collectively controlling 63.8% of the nation's capacity. Baowu Group is expanding through mergers and integration, leveraging TISCO's technological reserves to establish the world's most comprehensive stainless steel production base. The top five producers' market concentration (CR5) is projected to exceed 55%.Technological innovation targets high-end sectors, breaking further barriers in domestic substitution. Supported by policy funds, a nuclear-grade stainless steel production line will commence operations in 2025, filling a domestic gap and breaking Western monopolies. TISCO has developed ultra-thin semiconductor strip below 0.1mm with surface roughness controlled under Ra0.02μm, meeting wafer carrier requirements and driving this niche market to RMB8.5 billion. Green processes achieve parallel breakthroughs: electric arc furnace short-process smelting technology reduces unit energy consumption by over 10%, hydrogen-based steelmaking penetration exceeds 30%, and leading enterprises cut unit product carbon emissions by a further 4% compared to 2024. These technological advances propel high-end product demand to 45% of total output, with new energy vehicle steel applications leading growth.Facing market volatility, enterprises accelerated both internal and external development. While the domestic market saw volume growth but price declines—with crude steel output reaching 28.63 million tonnes in the first nine months, a 3.45% year-on-year increase—exports faced pressure from rising volumes and falling prices, with export value dropping by 23.3% in the first half of the year. In response, enterprises are simultaneously deepening engagement with emerging domestic demand. Firms like Qingshan and Delong are expanding capacity for 443 ultra-pure ferritic stainless steel to meet the surging demand for photovoltaic mounting structures, projected at 4.2 million tonnes. Concurrently, overseas market expansion continues, with exports reaching 4.12 million tonnes in 2024 and projected to rise to 4.38 million tonnes in 2025, prioritising infrastructure projects along the Belt and Road Initiative. Concurrently, enterprises have secured long-term agreements for nickel and chromium raw materials to hedge against price volatility risks.Currently, stainless steel enterprises are anchoring their development around green transformation, high-end specialisation, and globalisation, building new competitive advantages through capacity consolidation and technological breakthroughs. With the implementation of zero-carbon factories and advancements in high-end materials, the industry will gradually move beyond homogeneous competition, while leading enterprises will continue to enhance their global influence.
