en.Wedoany.com Reported - Recently, the 2.8 GPa grade high-strength and high-toughness maraging steel wire independently developed by China's Panzhihua Steel (Pangang) has been successfully applied in the consumer electronics field, becoming a core load-bearing structural component for a certain model of mobile phone. This marks China's pioneering global application of 2.8 GPa grade maraging steel in the consumer electronics sector, breaking through the global strength limit boundaries for the engineering and commercialization of ultra-high-strength maraging steel.
The iterative upgrading of ultra-high-strength maraging steel, often hailed as the "Pearl on the Crown of Steel," requires not only breaking through extreme strength limits but also balancing matching plasticity and toughness. This has long been a challenging technical difficulty in the global chemical materials field. To accelerate the marketization of the new 2.8 GPa grade maraging steel, Panzhihua Steel focused on dual-path research in fundamental studies and engineering preparation, completely overcoming the industry bottleneck where high strength and high plasticity/toughness are difficult to achieve simultaneously. They were the first to conquer the entire process key technology challenges for independent development and stable mass production of steel at this grade.
Relying on the pilot-scale "Technology Innovation Space" platform, the Panzhihua Steel R&D team innovatively optimized core processes such as cold drawing deformation, solution annealing, and surface finishing. This effort successfully resolved multiple technical challenges, including cold working and forming of ultra-high-strength steel wire, hardness control in the delivery state, dimensional accuracy assurance, and continuous stable production. Currently, this ultra-high-strength steel wire has achieved high-quality stable mass production for over 30 batches and was recognized as one of the first batch of new materials products in Sichuan Province for 2025 due to its excellent performance. Through in-depth cooperation with a well-known Chinese 3C electronics brand enterprise, Panzhihua Steel simultaneously tackled backend application technologies, successfully introducing the new material into key load-bearing structural components of a new phone model. This represents a "cross-boundary empowerment" of high-end metal materials in the consumer electronics field.
Industry insiders stated that this cross-industry application of Panzhihua Steel's 2.8 GPa grade ultra-high-strength steel not only demonstrates China's independent innovation capabilities in special steel materials but also opens a fusion channel between high-end metallurgical materials and the consumer electronics industry. It provides a new material solution for lightweight, high-strength, and high-reliability design in 3C products (computer, communication, consumer electronics), helping to accelerate the upgrade of the high-end manufacturing industry chain.
