Abstract: To adapt to the application trend of wall thickness reduction in N06625 for molten salt absorbers, the trial production of ultra-thin N06625 alloy tubes for molten salt absorbers was carried out through composition design and manufacturing process research. The chemical composition, mechanical properties, technological properties, corrosion resistance and dimensional accuracy of the trial-produced N06625 alloy tubes were inspected and tested. The results indicate that all the indicators of the trial-produced N06625 alloy tubes meet the design requirements, exhibit excellent overall performance and demonstrate substantial potential for industrial application. ?Its ultra-thin characteristic significantly reduces material costs, offering substantial economic advantages. This technological breakthrough will effectively promote the large-scale adoption of tower solar thermal power stations, while providing green thermal and electrical energy solutions for petrochemical, iron and steel, and other energy-intensive industries.
