小故事·大战略｜一块薄钢板，穿行-196℃能源极地

Core Viewpoint - Shandong Steel Group's Rizhao Company has successfully developed a full range of nickel-based steel, breaking foreign monopolies and ensuring the material's performance in extreme cold environments, crucial for LNG storage and transportation [1][3][5]. Group 1: Product Development and Technology - The nickel-based steel produced can withstand temperatures from -101°C to -196°C, essential for LNG applications [1][3]. - The company has developed a complete set of production processes for low-temperature nickel-based steel, achieving full domestic production capabilities after extensive testing [3][5]. - The 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 transport [5][6]. Group 2: Market Impact and Applications - The application of thin specifications in nickel-based steel has led to significant weight reductions in LNG storage tanks, enhancing safety and reducing material costs [5][6]. - The company has supplied nearly 30,000 tons of high-end nickel-based steel for national energy projects, generating nearly 700 million yuan in value [8]. - The largest LNG storage tank project globally, located in Zhuhai, utilized approximately 3,000 tons of nickel-based steel from Shandong Steel, demonstrating the product's effectiveness [6][8]. Group 3: Future Prospects and Challenges - The company aims to develop products with lower nickel content to reduce dependency on imported nickel, addressing potential supply chain risks [8]. - Shandong Steel's nickel-based steel products are expected to be recognized as one of Shandong Province's top ten technological innovations by 2025 [8].
