Chemical Properties
GH2747 Alloy Rod exhibits good resistance to various corrosive environments:
- Acids and Alkalis: Moderate resistance to acids like sulfuric and hydrochloric; performs better in dilute solutions.
- Oxidation: Exceptional resistance to oxidation at high temperatures, ideal for environments where Inconel 625 round bar might struggle.
- Environmental Limits: Not recommended for prolonged exposure to strong reducing acids or chlorides; performs best in oxidizing conditions up to 1300°C.
Things to Note (Limitations)
- Reducing Environments: Limited resistance to strong reducing acids or hydrogen sulfide environments; alternative alloys like UNS N08020 may be considered.
- Low-Temperature Toughness: Reduced ductility at cryogenic temperatures compared to Inconel 718 bar.
- Machining Challenges: Work-hardens during machining; requires slow speeds and sharp tools to avoid distortion.
- Cost: Higher cost compared to standard nickel alloy bars due to its specialized composition and processing.
Corrosion Data
| Environment | Corrosion Rate (mm/year) | Conditions | Notes |
|---|---|---|---|
| High-Temp Air (1000°C) | <0.005 | 1000°C, 12 months exposure | Excellent oxidation resistance |
| 10% Sulfuric Acid | 0.15 | 30°C, 3 months exposure | Moderate resistance |
| 10% Hydrochloric Acid | 0.2 | 25°C, 1 month exposure | Not recommended for prolonged exposure |
| Atmospheric (Coastal, Humid) | 0.01 | 25°C, 12 months exposure | Slight surface corrosion; coating advised |
| 5% Sodium Hydroxide (Alkaline) | 0.02 | 40°C, 3 months exposure | Good resistance |
| Sulfur-Containing Gas (800°C) | 0.03 | 800°C, 6 months exposure | Superior to Inconel bar stock |
Welding and Manufacturing Tips
- Welding: Use TIG or MIG welding with matching nickel alloy filler metals. Preheating is not required; post-weld heat treatment at 600–700°C can relieve stresses.
- Forming: Best formed in the annealed state; hot working should be done between 1050°C and 1200°C.
- Machining: Use carbide tools at low speeds with heavy feeds; suitable for producing high nickel alloy round bars but requires careful handling.
- Heat Treatment: Solution treatment at 1150°C followed by air cooling enhances high-temperature properties.
