# GH4099

> High-tungsten Ni-based alloy for welded combustion chamber and flame tube assemblies.

GH4099 is a Chinese tungsten-strengthened nickel-based superalloy with excellent weldability for fabricating combustion chamber and flame tube assemblies. The high tungsten content provides solid-solution strengthening at elevated temperatures, and the alloy can be welded in the solution-treated condition.
