Driven by the \"dual carbon\" goals, China’s hydrogen industry has seen explosive growth in recent years. Leveraging its extensive expertise in the metallurgy field, Shougang Jingtang has successfully developed a full range of hydrogen transport pipeline steels of grades B/X42/X52/X60/X65MH. It has overcome six key technical challenges, including those related to hydrogen embrittlement and low-temperature toughness, thus creating a relatively comprehensive portfolio of hydrogen transport pipeline steel products. This matrix covers a variety of steel grades and application scenarios, providing a solid foundation for overcoming the key challenge of \"inter-regional transportation\" in China’s hydrogen industry. Hydrogen transmission pipelines are the \"major arteries\" of the hydrogen energy industry, and they serve as the key infrastructure for overcoming challenges related to cross-regional hydrogen distribution and promoting coordinated development across the entire industry chain. As the **hydrogen energy strategy is implemented at an accelerated pace, Shougang seizes the opportunities presented by the energy revolution by focusing on the research and development of a full range of hydrogen transport pipeline steels, thereby using technological innovation to meet the demands of this strategy.** During the research and development process, Shougang adopted an innovation-driven approach that combined internal collaboration with external coordination. Units such as Shougang Jingtang, the Technology Research Institute, and the Corporate Marketing Center worked together efficiently, uniting forces from upstream and downstream segments of the industry chain—including tube manufacturing companies, hydrogen energy users, and research institutions—to create a unified effort for innovation through integration of industry, academia, research, and practical application. Leveraging its technical expertise in pipeline steel, the team successfully overcame six key challenges, ultimately resolving the issue of hydrogen embrittlement in hydrogen transport pipeline materials. The entire range of hydrogen transport pipeline materials produced meet the requirements for resistance to hydrogen embrittlement, high strength and toughness, as well as good weldability. The product has passed tests conducted by authoritative institutions, demonstrating compatibility with hydrogen environments, and is perfectly suitable for high-pressure pure hydrogen/hydrogen-blended transportation applications. From molten steel production to final product inspection, Shougang Jingtang ensures quality control throughout the entire process. By integrating previous experience in hydrogen doping and the development of pure hydrogen delivery pipelines, and by continuously optimizing the steelmaking and rolling processes, a comprehensive control system covering the entire production and quality inspection process has been established. The R&D, production, and sales teams work closely to meet customer needs; through multiple rounds of revisions to technical documents and rigorous reviews, they build trust with solid data, laying a solid foundation for the successful implementation of the products. The successful development and mass production of Shougang’s full range of hydrogen transport pipeline products represent an important milestone in the company’s efforts to advance in the field of new energy. As a customized innovation in the field of hydrogen energy transmission, it not only demonstrates Shougang’s strong capabilities in the development of special steels, but will also provide significant impetus for the transformation of China’s energy structure. In the future, Shougang will continue to leverage technological innovation to support the clean energy industry, providing a stronger “steel framework” for the development of the entire hydrogen energy sector.
