Nickel-based N155 alloy has a long history, back to 1950, of high strength at temperatures up to 1500 F and is capable of sustaining moderate loading at temperatures of 2000 F. It has good oxidation resistance at high temperature and also possesses good corrosion resistance to sulfuric acid (at room temperature) and to nitric acid. High temperature strength derives directly from the chemical composition of the alloy and is not dependent upon age hardening.

Application: Oxidation resistance nickel alloy N-155 used in Industrial furnace structural parts and fixtures. High temperature bolts and gas turbine combustion chambers, exhaust manifolds, and turbine blades. N-155 alloy is used in numerous aircraft applications such as tail cones and tailpipes, exhaust manifolds, combustion chambers, afterburners, turbine blades and buckets, and bolts.

Forming by cold working is preferred and the high strength N155 nickel alloy has good ductility. It does work harden and may require a solution heat treatment to restore ductility during cold forming.
