Nimonic 80 and Nimonic 80A are nickel-base alloys containing a high percentage of chromium, with aluminum and titanium as hardening agents. They are made to the same compositional specification, but Nimonic 80A is produced to meet a more severe requirement with respect to resistance to creep when stressed at higher temperatures than Nimonic 80. Both alloys show high strength at high temperature levels and are very resistant to scaling, oxidation, heat and corrosion. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as creep. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: Ni-10.
