Please find the material data sheet on the VDM® Alloy 80 A microsite.

 

The ability to be hardened is achieved by means of admixtures of titanium and aluminum. It can be delivered in a solution-annealed or age-hardened condition. The alloy is generally used in an age-hardened state.

VDM® Alloy 80 A (2.4952/N07080) has a high resistance to oxidation under cyclic temperature changes. The alloy forms a firmly adhering oxide layer (Cr2O3), which protects against progressive corrosion and oxidation attacks. The alloy is resistant to scaling up to 1,000 °C (1,832 °F). The material has proven its resistance to vanadium pentoxide, sodium and sulphur com-pounds for exhaust valves in engines operated with heavy oil.

Due to its excellent resistance to creep and due to its high resistance to fatigue at temperatures up to 815 °C (1,500 °F) as well as the very good resistance to oxidation, VDM® Alloy 80 A is used for components such as blades, rings and washers in gas turbines. Additional applications are connecting elements, exhaust valves in combustion engines and other highly stressed components which are used in the aforementioned temperature range, such as brackets for boiler pipes, inserts in castings or high temperature springs.
