Product Overview
Hastelloy C276 bright solid bar is a high-performance nickel-based alloy product with outstanding properties. In the aerospace industry, components need to withstand extreme conditions such as high temperatures, high pressures, and strong corrosive media during flight. The excellent oxidation resistance ensures stability and safety of aerospace parts, reducing the risk of component failure caused by oxidation and corrosion.
In the petrochemical industry, where equipment is often exposed to various corrosive chemicals during oil and gas exploration, refining, and chemical production processes, the polished surface provides better corrosion resistance and reduces fluid resistance in pipelines, improving production efficiency.
Chemical Composition
Main Elements
- Nickel (Ni): Base element providing excellent basic corrosion resistance and mechanical properties, ensuring stability at high temperatures
- Chromium (Cr): 14.5% - 16.5% - Enhances corrosion resistance in oxidizing environments by forming a stable chromium-oxide film
- Molybdenum (Mo): 15.0% - 17.0% - Improves corrosion resistance in reducing environments and enhances resistance to strong acids
Trace Elements
- Iron (Fe): 4.0% - 7.0% - Added to reduce costs while maintaining excellent corrosion-resistant properties
- Tungsten (W): 3.0% - 4.5% - Enhances corrosion resistance in chloride environments and increases strength and hardness
Chemical Composition Table
| Element | Content Range (%) |
|---|---|
| Nickel (Ni) | Balance |
| Chromium (Cr) | 14.5 - 16.5 |
| Molybdenum (Mo) | 15.0 - 17.0 |
| Iron (Fe) | 4.0 - 7.0 |
| Tungsten (W) | 3.0 - 4.5 |
| Carbon (C) | ≤0.08 |
| Manganese (Mn) | ≤1.0 |
| Silicon (Si) | ≤1.0 |
| Phosphorus (P) | ≤0.040 |

Oxidation Resistance
Hastelloy C276 demonstrates excellent oxidation resistance through the formation of a dense chromium-oxide film that acts as a physical barrier against further oxygen diffusion. At 800°C in air-rich environments, weight gain due to oxidation is only about 0.01 g/cm² after 100 hours of continuous exposure.
This property ensures reliable performance in aerospace turbine engine parts operating at temperatures up to 900°C and in petrochemical high-temperature reactors, maintaining structural integrity and reducing maintenance requirements.
Polished Surface Benefits
Surface Treatment Processes
- Mechanical Polishing: Uses abrasive materials and polishing wheels for general surface improvement
- Electrolytic Polishing: Produces uniform, mirror-like finish without mechanical stresses
- Chemical Polishing: Uses chemical solutions for complex geometries and moderate polish
Key Advantages
- Enhanced Corrosion Resistance: Smooth surface reduces sites for corrosive substance accumulation
- Improved Aesthetic Appeal: Professional appearance for visible components
- Reduced Impurity Adhesion: Minimizes particle accumulation in pipelines and engine components
Industry Applications
Aerospace Applications
- Turbine Engine Components: Withstands high rotational speeds and temperature gas flows up to 1000°C
- Combustion Chamber Liners: Resists intense heat and corrosive combustion products
- Exhaust Systems: Maintains structural integrity during thermal cycling and high-temperature exhaust gases
Petrochemical Applications
- Pipelines: Resists corrosive fluids including sulfur-containing crude oil and chemical reagents
- Valves: Withstands aggressive chemical environments in valve bodies, stems, and seats
- Reactors: Maintains structural integrity under high-temperature and high-pressure chemical reactions
Conclusion
Hastelloy C276 bright solid bar offers a unique combination of properties including outstanding corrosion resistance, high-temperature strength, and excellent mechanical properties. Its adherence to international standards and versatile applications in aerospace and petrochemical industries make it a reliable choice for demanding environments where performance, safety, and longevity are critical.
