On December 11, Gelonghui reported that Gan Su Jiu Steel Group Hong Xing Iron & Steel Co,Ltd (600307.SH) stated at the performance briefing that the fourth-generation stainless steel for Nuclear Power fast reactors developed independently by the company has successfully replaced imported materials, solving the "bottleneck" problem in China's Nuclear Power engineering field, and has been supplied to key national Nuclear Power station construction projects. The self-developed low expansion iron-nickel Alloy has a small thermal expansion coefficient and good dimensional stability, replacing imported materials, and is mainly applied in Aviation, microwave communication, and container transportation for oil and Henry Hub Natural Gas, among others. The successfully developed low-temperature liquid hydrogen special stainless steel has been tested by authoritative Institutions, and various Indicators meet the requirements for hydrogen storage steel, and cooperation has been initiated on a liquid hydrogen tank manufacturing project. The successfully developed 347H product for high-temperature storage tanks in solar thermal molten salt power stations is widely used in solar thermal power station projects in the central and western regions. The carbon steel hot-rolled product series, bridge steel strips, weathering steel, and coated series products such as zinc-aluminum-magnesium are applied to the two new projects. In the future, the company will focus on the construction progress of the two new projects, actively connect, and realize the incremental application of the company's Steel products in these projects.
