SynopsisBaosteel's Heavy Plate Division achieves a groundbreaking milestone by delivering the world's widest 18MND5 steel plates for critical equipment in a nuclear power project. This achievement signifies a significant advancement in China's nuclear power steel industry. Baosteel's commitment to localization and innovation has led to the complete "Made in China" production of vital components, strengthening the nation's stance in sustainable energy.ArticleBaosteel's Heavy Plate Division has accomplished an extraordinary feat in the nuclear power sector, marking a significant advancement in China's steel industry. The division successfully delivered the world's widest 18MND5 steel plates for critical equipment in a nuclear power project, solidifying its mission to enhance the localization of nuclear power equipment.The nuclear industry demands precision and safety, and the choice of materials is crucial. 18MND5 steel plates are used in the shells and pedestals of key equipment within the nuclear island due to their wide dimensions, significant weight, and high-performance requirements. However, manufacturing such steel plates is a formidable challenge.Until recently, very few manufacturers in China or globally possessed the capability to produce 18MND5 steel plates for nuclear power applications. These plates were primarily sourced from a single European steel manufacturer, creating a monopoly in the industry.In December 2017, Baosteel officially took on the task of domesticating the production of 18MND5 steel plates for a nuclear power project. The company's Nuclear Power Steel Team, drawing on years of expertise in core steel technologies for nuclear power components such as AP1000 and CAP1400, played a pivotal role in achieving the goal of full localization. In 2022, they once again contributed to achieving complete localization for another nuclear power project.In August 2023, Baosteel's Heavy Plate Division accomplished the delivery of the world's widest 18MND5 steel plates for critical equipment, a testament to the team's dedication, innovation, and unwavering commitment. This achievement not only reflects their steelmaking prowess but also embodies their dedication to serving the nation.Baosteel's journey doesn't end here. They are determined to push the boundaries further in the pursuit of "high-end" nuclear power equipment. To ensure the safety and advanced capabilities of a domestic nuclear power station project, the design specifications for 18MND5 steel plates have been elevated in terms of size, weight, and mechanical performance. One such requirement, "the tensile strength of steel plates after delivery and simulated post-weld heat treatment shall not be less than 600MPa," posed a significant technical challenge.Baosteel's Nuclear Power Steel Team embraced this challenge with a sense of duty and innovation. To meet the stringent criteria, they meticulously designed a production process that involved smelting continuous cast ingots at the Baoshan base, partnering with electric slag remelting steel ingots, rolling 5m-thick plates at the Baoshan base, and performing quenching and tempering heat treatment. Quality control measures were enforced at every step, and continuous optimization was carried out during production. Facing the exacting technical demands, the team left no stone unturned in ensuring that the steel plates met the high-temperature tensile performance requirement. They achieved mastery in the high-performance 18MND5 steel plate production technology, successfully supplying the steel plates for a Phase I project in 2018 and the heads and barrels of the nuclear power plant's critical equipment in 2022.Currently, Baosteel is smoothly progressing with the production of 18MND5 steel plates for nuclear power equipment, with over half of the deliveries already completed. Recently, Baosteel secured a contract for 18MND5 steel plates for a Phase I project.With the approval of a new project based on China's third-generation nuclear power technology, Baosteel will continue collaborating closely with its strategic partners. They aim to provide a comprehensive solution for the rapid manufacturing of critical equipment for China's nuclear power nation-building effort, contributing their steel expertise to this vital national endeavor.Conclusion:Baosteel's achievement in delivering the world's widest 18MND5 steel plates for nuclear power equipment signifies a remarkable milestone in China's nuclear power industry. Their commitment to localization and innovation has led to the complete "Made in China" production of critical nuclear components. Baosteel's dedication to advancing nuclear power technology and safety underscores their pivotal role in supporting China's nuclear power nation-building initiative.
