一块薄钢板，穿行-196℃能源极地！山钢日照全规格镍系钢打破国外垄断

Core Viewpoint - The article highlights the advancements made by Shandong Steel Group Rizhao in producing nickel-based steel, which is essential for storing and transporting liquefied natural gas (LNG), emphasizing the shift from reliance on imports to domestic production capabilities [1][2][3]. Group 1: Production and Technology - Shandong Steel Rizhao has developed a complete set of production processes for low-temperature nickel-based steel, achieving full domestic production capabilities after extensive testing [2]. - The nickel-based steel product line includes various nickel content levels (9Ni, 7Ni, 5.5Ni), with thickness capabilities ranging from 5mm to 50mm, meeting all specifications for LNG storage and transportation [2][3]. - The company has achieved world-leading standards in manufacturing thin steel plates, maintaining a thickness tolerance of ±0.05mm [2]. Group 2: Market Impact and Applications - The price of nickel-based steel has significantly decreased due to technological breakthroughs, allowing for lighter and safer LNG storage tanks by replacing thicker steel plates with thinner ones [3]. - The application of these thin steel products has been validated in major projects, such as the world's largest single LNG storage tank in Zhuhai, which utilized approximately 3,000 tons of nickel-based steel, resulting in a weight reduction of up to 37% [3]. - Shandong Steel Rizhao has supplied nearly 30,000 tons of high-end nickel-based steel for various national energy projects, generating nearly 700 million yuan in value and supporting the stability of the national energy storage and transportation industry [3]. Group 3: Future Developments - By 2025, Shandong Steel Rizhao's full range of nickel-based steel products is expected to be recognized as one of Shandong Province's top ten technological innovations [4]. - The company is focusing on developing products with lower nickel content to reduce manufacturing costs and dependence on imported nickel resources, thereby enhancing national energy storage and transportation security [4].
