Introduction

GH1131 Superalloy (GH113) is a solid-solution strengthened iron-nickel base superalloy reinforced with W, Mo, Nb, and N. With 28% nickel, it offers high thermal strength and good process performance among low-nickel high-temperature alloys. It is used for rocket engine and aero engine parts such as afterburner components. However, it has lower oxidation resistance and structural stability than similar nickel-based alloys; after long-term use at 700–900°C, plasticity and formability may decrease. Available in round bar, sheet, plate, strip, wire, and forgings per GB/T standards.

Advantages

(1) High temperature strength: As a solid-solution strengthened iron-nickel base superalloy reinforced with W, Mo, Nb, and N additions, GH1131 round bar and forging deliver excellent yield strength and creep resistance at elevated temperatures.

(2) Good process performance: GH1131 sheet and strip offer good weldability and hot plasticity, enabling fabrication of complex aero engine afterburner components.

(3) Low nickel content (28%): This alloy maintains high‑temperature strength while using less nickel than many superalloys, providing a cost‑effective solution for moderate‑temperature applications.

(4) Good workability: GH1131 wire and welding wire are readily formed and joined, making them suitable for rocket engine parts and structural components.

(5)Wide product availability: Supplied as round bar, sheet, plate, strip, wire, tube, and forgings per GB/T standards, with custom sizes available.

Note: Compared to nickel‑rich superalloys, GH1131 has lower oxidation resistance and structural stability. After long‑term service at 700–900°C, room temperature plasticity and formability may decrease.

Applications

(1)Rocket engine components – GH1131 seamless tube and forging are used in thrust chambers, nozzle extensions, and gas generator parts operating up to 1000°C.

(2)Aero engine afterburner parts – GH1131 sheet and strip serve in afterburner adjustable nozzle housings, flame holders, and mixing ducts.

(3)High‑temperature structural parts – GH1131 round bar and plate are applied in gas turbine casings, transition ducts, and support rings where moderate strength is sufficient.

(4)Exhaust system components – GH1131 wire and fastener are specified for jet engine exhaust manifolds and tail cones.

(5)Industrial furnace fixtures – GH1131 plate and forging are used in heat treating baskets, retorts, and furnace muffles for intermittent high‑temperature service.
