W.Nr 1.4980


Turbine engine components, Afterburner parts, non-magnetic cryogenic equipment, springs, oil & gas manifolds


Incoloy® Alloy A-286 is an age-hardenable Iron-Nickel-Chromium alloy with high strength and corrosion resistance at elevated temperatures. These properties are maintained up to about 1300°F (700°C). 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. In the age-hardened condition, A-286 has high strength at room temperature and good creep-rupture strength during extended high-temperature exposure.
