Incoloy Alloy A286

Incoloy Alloy A286

General

This material is an iron-nickel-chromium alloy with additions of molybdenum and titanium. It is precipitation hardenable for high mechanical properties. The alloy maintains good strength and oxidation resistance at temperatures up to 1300 degrees Fahrenheit (700°C). The alloy is austenitic in all metallurgical conditions. The high strength and excellent fabrication characteristics of A286 make the alloy useful for various components of aircraft and industrial gas turbines. Applications include blades, vanes, shafts, tail cones, afterburners, springs, and all types of screwed fasteners.
