行业协会：雅江工程将带来400万-600万吨钢铁超级订单

Core Insights - The Yarlung Tsangpo River downstream hydropower project is set to officially commence construction on July 19, 2025, with a total investment of 1.2 trillion yuan and an installed capacity of 70-81 million kilowatts, equivalent to three Three Gorges power stations [1] - This project is a key component of China's "West-to-East Power Transmission" strategy and presents a historic opportunity for the steel industry, creating a demand for tens of millions of tons and driving technological upgrades [1] Steel Demand Overview - The steel demand for the Yarlung project will cover the entire construction cycle, involving civil engineering, equipment, and transmission, with an estimated total demand for special steel reaching 4-6 million tons, accounting for 1.2% of the national crude steel output in 2024 [1][2] - This demand significantly exceeds the Three Gorges project, which required 590,000 tons of steel, driven by three main factors: the project's scale, extreme environmental requirements, and the expansion of supporting infrastructure [2] Special Steel Characteristics - High-end special steel will be the primary focus for the Yarlung project, with demand characterized by "specialization, high strength, and long lifespan" [3] - Estimated steel usage includes: 60-70% for main structure (2.4-4.2 million tons), 15-20% for underground works (600,000-1.2 million tons), 10-15% for electromechanical equipment (400,000-900,000 tons), 5-10% for construction aids (200,000-600,000 tons), and 5% for other special-purpose steel (200,000-300,000 tons) [3] - Key types of steel include high-strength rebar, special medium-thick plates for hydropower, non-oriented silicon steel sheets, weather-resistant angle steel, and special stainless steel, all designed to withstand extreme conditions [3]
