Characteristics of N-155 Alloy
N-155 Alloy delivers exceptional high-temperature performance without relying on age hardening. It is well-suited for components exposed to high stresses up to 1500°F and can endure temperatures up to 2000°F under moderate stress. The alloy combines excellent ductility with outstanding oxidation resistance, while remaining easy to fabricate and machine.
Thanks to its strength and corrosion resistance at elevated temperatures, N-155 is widely used in aerospace and defense industries. Typical applications include tail cones, tailpipes, exhaust manifolds, combustion chambers, afterburners, turbine blades, turbine buckets, and high-temperature fasteners.

Heat Treatment:
Solution Treatment: Heat the alloy to 2100–2280°F, hold at temperature for 1 hour, and then cool rapidly. Processing at the lower range enhances ductility, while the higher range maximizes rupture strength.
Aging Treatment: Heat to 1400–1500°F, maintain for about 16 hours, and then air cool to achieve optimum mechanical properties.
