1. Introduction to GH3044 Materials
GH3044 superalloy is a Ni-Cr solid-solution strengthened wrought superalloy applicable for service temperatures below 900℃. It contains high tungsten content plus a small amount of aluminum and titanium. The alloy features high plasticity, moderate high-temperature strength, excellent oxidation resistance, superior stamping and welding workability. It is widely used for long-term service aero-engine main combustion chamber and afterburner components, as well as heat shields and guide vanes. Available product forms: plates, strips, wires and rings.

4. GH3044 processing performance
GH3044 forming performance
Heating temperature for alloy ingot forging: 1170℃±10℃, finish forging temperature no less than 900℃. Slab rolling heating temperature: 1190±10℃; hot rolling heating temperature for thin sheets: 1130℃±10℃, finish rolling temperature ≥800℃. Total cold rolling reduction ratio for thin sheets is approximately 30%.
GH3044 sheets possess excellent stamping performance. The limiting drawing coefficient K limit of cold rolled thin sheets in delivery state equals 2.06.
GH3044 component heat treatment process
Intermediate heat treatment: 1140℃±10℃, hold for 3~5 minutes, air cool. Final heat treatment depends on service conditions of parts. Parts requiring outstanding thermal fatigue resistance: solid solution at 1150℃, hold 3~5 minutes, air cool; parts requiring high high-temperature strength: solid solution at 1200℃, hold 3~5 minutes, air cool.
5. GH3044 application fields
Suitable for high-temperature structural components, heat shields, guide vanes operating continuously below 900℃.
