Features

The Cr content in the alloy accounts for about 23%, and the carbide forming elements such as tantalum, tungsten and titanium are added at the same time, so the alloy has excellent heat-resistant corrosion resistance and high temperature strength.

Applications

The alloy is only used to make hot end components such as gas turbine engine turbine blades working below 1050 degrees. It is recommended to be applied to engines with harsh service conditions such as aeroengines and advanced marine engines
