Nimonic Alloy 80A
Material Data Sheet
Nimonic® Alloy 80A is a wrought, age-hardenable nickel-chromium alloy, strengthened by additions of titanium, aluminum, and carbon, developed for service at temperatures up to 1500°F (815°C). It is produced by high-frequency melting and casting in air for forms to be extruded. Electroslag refined material is used for forms to be forged. Vacuum refined versions are also available. Recommended filler metal for Nimonic® alloy 80A is Nimonic® 90. A prerequisite for welding is that the metal should be solution treated. Fusion welding by tungsten inert gas welding and metal inert gas welding methods are both suitable for this alloy.
Nimonic® alloy 80A can be hot worked at temperature ranges of 1920-2190°F (1050-1200°C) and hot forged at temperatures in the range of 1800-2150°F (982-1176°C).
