Comparison of ASTM B407 N08810 Nickel Alloy with Other Materials
VS N08800: For operating temperatures below 600°C, the difference between N08810 and N08800 is minimal. However, above 650°C, especially in high-temperature environments subject to mechanical stress, N08810's creep resistance becomes crucial. N08800, however, lacks high-carbon control and heat treatment, resulting in lower high-temperature strength.
VS N06600: N06600 alloy has a higher nickel content and offers superior resistance to alkaline corrosion and chloride-ion stress corrosion cracking, but its high-temperature strength and carburization resistance are generally lower than N08810.
VS N08825: N08825 alloy contains molybdenum and copper. It was designed to withstand complex wet corrosion environments such as sulfuric acid, phosphoric acid, and chloride-containing solutions, but its high-temperature strength is significantly lower than that of N08810.
Preparation process: melting, casting, heat treatment (such as annealing, generally carried out between 1120~1170 ℃ to strengthen the grain and change its creep resistance and stress fracture performance), cold processing, etc.
Processing precautions: During the cold rolling process, careful operation is necessary to avoid serious damage to the outer surface of the pipe; After cold rolling, it needs to go through processes such as acid washing and polishing to remove oxide scale and defects
