N-155 alloy has good high-temperature strength, which is inherent in the material itself and does not require age hardening to achieve.

N-155 alloy is suitable for working conditions that require high stress at temperatures up to 1500 ° F, and can be used at temperatures up to 2000 ° F with moderate stress loads. This alloy has good ductility, excellent oxidation resistance, and is easy to process.
