INCOLOY® alloy A-286 (UNS S66286/W. Nr. 1.4980) is an iron-nickel-chromium alloy with additions of molybdenum and titanium. It is agehardenable for high mechanical properties. The alloy maintains good strength and oxidation resistance at temperatures up to about 1300°F (700°C).
The Incoloy alloy A-286 is austenitic in all metallurgical conditions. The high strength and excellent fabrication characteristics of Incoloy alloy A-286 make the alloy useful for various components of aircraft and industrial gas turbines. It is also used for fastener applications in automotive engine and manifold components subject to high levels of heat and stress and in the offshore oil and gas industry. Incoloy alloy A-286 is also suited for use up to a temperature of about 1300 F in corrosive environment (such as gas turbines) and to 1500 F for continuous service in oxidizing environments.
