GH3044, GH3039, GH39, and GH44 are high-grade nickel-based superalloy steels engineered for superior performance in high-temperature and high-stress environments. These materials are widely used in aerospace, chemical processing, marine, and thermal power industries due to their exceptional mechanical strength, thermal stability, and oxidation resistance.
Superalloys like GH3044 and GH3039 are designed to withstand extreme operational conditions. They maintain structural integrity at elevated temperatures, making them ideal for turbine blades, heat exchangers, reactor components, and high-pressure piping systems. Their chemical compositions ensure long-term resistance to corrosion and creep deformation.
Our superalloy steels are available in a variety of forms including seamless pipes, precision tubes, forged bars, and round rods. Each form is manufactured with strict quality control to meet international engineering standards.
| Grade | Typical Chemical Composition (%) | Operating Temperature (°C) | Common Applications |
|---|---|---|---|
| GH3044 | Ni 74, Cr 15, Fe 6, Al 3, Ti 1 | Up to 950°C | Combustion chambers, gas turbines |
| GH3039 | Ni 68, Cr 19, Fe 8, Ti 2, Al 1 | Up to 850°C | Heat-resistant fasteners, exhaust systems |
| GH39 | Ni 72, Cr 17, Fe 6, Ti 2, C 0.08 | Up to 900°C | Industrial heaters, high-temp bearings |
| GH44 | Ni 76, Cr 14, Fe 6, Al 2, Ti 1 | Up to 1000°C | Aerospace parts, thermal shielding |

Custom sizing is available upon request. Below is our standard product range:
| Form | Diameter (mm) | Length (mm) | Tolerance |
|---|---|---|---|
| Pipe | 8 – 150 | 1000 – 6000 | ±0.2mm |
| Tube | 6 – 120 | 1000 – 6000 | ±0.1mm |
| Bar | 10 – 200 | Cut to length | ±0.3mm |
| Rod | 6 – 100 | Cut to length | ±0.2mm |
These alloys are commonly used in high-temperature environments such as gas turbines, jet engines, and chemical reactors. Their strength and oxidation resistance make them suitable for components that undergo thermal cycling and high mechanical loads.
Yes. While superalloys require specialized techniques for optimal results, GH series materials exhibit good weldability and machinability when proper tools and parameters are applied.
Absolutely. We support custom dimensions, special packaging, and worldwide delivery, including DDP/DDU terms upon request.
Our GH series superalloys conform to national and industry standards such as GB/T, GJB, and equivalent ISO specifications. Material certificates and test reports are provided with each batch.
