NICKEL ALLOY A-286
DESCRIPTION
Nickel Alloy A-286 (UNS S66286) is iron-nickel-chromium based austenitic material with additions of molybdenum and titanium. Nickel Alloy A-286 is known for maintaining good strength and oxidation resistance, especially at temperatures up to 1300°F (700°C). Nickel Alloy A-286 has high ductility and excellent fabrication characteristics.
Nickel Alloy A-286 is solution annealed at 982°C (1800°F), This heat treatment improves the strength of the alloy.
