GH3128 nickel alloy wire is a high-performance material specifically engineered for use in demanding high-temperature and corrosive environments. As a Ni-Cr-based superalloy, GH3128 exhibits exceptional resistance to oxidation, stress corrosion, and thermal fatigue. It delivers stable mechanical strength and long-term performance at elevated temperatures up to 1050°C, making it a preferred choice in aerospace engine parts, industrial heating systems, nuclear installations, and high-precision electrical components.
Excellent oxidation resistance and thermal stability in continuous service up to 1050°C
High tensile and creep rupture strength at elevated temperatures
Good weldability and formability for complex fabrication requirements
Reliable corrosion resistance in oxidizing and carburizing atmospheres
Outstanding structural integrity under cyclic loading and thermal shock
The chemical makeup of GH3128 is critical to its high-temperature resistance and structural performance. The following table outlines its typical composition:
| Element | Content (%) |
|---|---|
| Nickel (Ni) | 58.0 – 63.0 |
| Chromium (Cr) | 20.0 – 23.0 |
| Iron (Fe) | ≤ 3.0 |
| Molybdenum (Mo) | 4.0 – 6.0 |
| Tungsten (W) | 2.0 – 3.0 |
| Cobalt (Co) | ≤ 2.0 |
| Carbon (C) | ≤ 0.10 |
| Manganese (Mn) | ≤ 0.50 |
| Silicon (Si) | ≤ 0.50 |
GH3128 offers stable mechanical performance under high thermal stress, making it suitable for applications involving rapid temperature shifts or sustained high-heat exposure:
| Property | Typical Value | Condition |
|---|---|---|
| Tensile Strength | ≥ 830 MPa | Room Temperature |
| Yield Strength | ≥ 450 MPa | Room Temperature |
| Elongation | ≥ 20% | Room Temperature |
| Hardness | 220–260 HB | Annealed |
| Working Temperature | Up to 1050°C | Continuous Use |
We provide GH3128 wire in a variety of sizes, surface finishes, and delivery forms to suit diverse industrial needs:
| Diameter (mm) | Condition | Surface Finish | Delivery Form |
|---|---|---|---|
| 0.05 – 8.00 | Annealed / Cold Drawn | Bright / Oxidized / Polished | Coils / Spools / Cut Length |
GH3128 wire is trusted in extreme environments across multiple industries, due to its consistent performance and durability:
Aerospace: Turbine engine parts, combustion liners, high-temperature fasteners
Industrial Furnaces: Electric heating elements, thermocouple protection, resistance wires
Power Generation: Boiler components, exhaust heat shields, superheater tubes
Nuclear Industry: Structural parts in radiation-exposed environments
Electronics: High-temp leads, sensors, and precision control systems
GH3128 offers superior creep strength and oxidation resistance at temperatures exceeding 1000°C. It also provides enhanced microstructural stability, making it ideal for aerospace and thermal processing sectors.
Yes. GH3128 has good weldability and is compatible with standard nickel-base welding consumables. It can also be machined using carbide tools and proper cooling, although it's best processed in solution-annealed condition.
Yes. We offer customized labeling, heat number tracking, and export-ready packaging (wooden cases, vacuum packing, anti-rust oil wrapping) to meet global supply chain requirements.
We provide Mill Test Certificates (EN 10204 3.1/3.2), chemical and mechanical test reports, and can comply with ASTM, DIN, AMS, GB, and customer-specific standards.
Strict quality control from raw material to final product
Fast delivery and global logistics support
Custom processing and OEM/ODM options
Responsive technical service and after-sales support
