Introduction

GH3039 Superalloy (GH39) is a single-phase austenitic solid-solution strengthened nickel-chromium based superalloy with moderate thermal strength and good thermal fatigue performance below 800°C, and excellent oxidation resistance up to 1000°C. It offers good cold formability, good weldability, and a stable microstructure for long-term service below 850°C. Ideal for aircraft engine combustion chambers, afterburner components, and gas turbine casings. Available in sheet, plate, bar, wire, tube, and forgings per GB/T, ASTM, AMS, or BS standards.

Advantages

(1)Excellent high temperature oxidation resistance up to 850°C: GH3039 nickel based superalloy forms a stable protective oxide layer, preventing scaling and extending service life in gas turbine combustion chambers and afterburner components.

(2)Good solid solution strengthening with Mo and Al: GH3039 round bar and sheet maintain stable tensile strength and creep resistance under prolonged thermal exposure, reducing deformation in thin-walled structures.

(3)Outstanding cold formability and weldability: GH3039 alloy wire and strip enable complex stamping, deep drawing, and argon arc welding without post-weld heat treatment cracks, ideal for aircraft engine parts.

(4)High thermal fatigue resistance:GH3039 superalloy plate withstands rapid temperature cycling from room temperature to 850°C without thermal cracking, suitable for flame tubes and transition ducts.

(5)Excellent resistance to fuel gas corrosion: GH3039 seamless tube and pipe resist sulfidation and vanadium attack in high sulfur fuel environments, ensuring reliable performance in marine and industrial gas turbines.

Applications

(1)Aero engine combustion chamber parts – GH3039 sheet and strip are widely used for flame tubes, louver panels, and connecting rings in jet engines requiring high temperature oxidation resistant alloy.

(2)Gas turbine afterburner components – GH3039 nickel base alloy is specified for tail cones, flame holders, and spray bars where thermal shock resistance and hot corrosion protection are critical.

(3)Heat exchangers and exhaust systems – GH3039 seamless tube serves in high temperature recuperators and exhaust piping for industrial gas turbines and power generation equipment.

(4)Turbocharger housings and heat shields – GH3039 plate and bar offer reliable creep strength and oxidation barrier for heavy duty diesel and marine engines operating up to 800°C.

(5)Chemical and petrochemical furnace parts – GH3039 alloy wire and mesh are applied in radiant tubes, retorts, and catalyst grids requiring good resistance to oxidizing and carburizing atmospheres.
