The alloy has good thermal strength, high plasticity, cold and hot fatigue and oxidation resistance, and has good cold stamping and welding process properties. The alloy is single-phase austenite after solution treatment, and the microstructure temperature during use.


The alloy is mainly used for turbine engine combustion chamber components working below 800 ℃. High temperature parts requiring oxidation resistance but bearing small load below 1100 ℃.
