Chemical Properties
The cobalt-chromium alloy in L605 Cobalt Alloy Pipe offers excellent resistance to acids, alkalis, and oxidative environments. It performs well against sulfuric and hydrochloric acids but may require caution in highly concentrated alkaline solutions. Environmental restrictions include avoiding prolonged exposure to molten salts or halogen-rich atmospheres.
Things to Note (Limitations)
While L605 Cobalt Alloy Pipe is highly durable, certain limitations should be noted:
- High-Temperature Fatigue: Prolonged exposure above 2000°F may reduce fatigue life.
- Brittle in Specific Conditions: Susceptible to embrittlement in sulfur-rich environments.
- Cost: Higher cobalt alloy price compared to stainless steel alternatives.
Corrosion Data for L605 Cobalt Alloy Pipe
| Environment | Corrosion Rate (mm/year) |
|---|---|
| Atmospheric (Rural) | <0.01 |
| Seawater | 0.02–0.05 |
| 10% Sulfuric Acid | 0.1–0.3 |
| 5% Hydrochloric Acid | 0.2–0.5 |
Best Welding and Manufacturing Practices
L605 Cobalt Alloy Pipe supports various welding methods, including:
- TIG Welding: Preferred for precision and clean welds.
- Plasma Arc Welding: Suitable for thin-walled pipes.
- Electron Beam Welding: Ideal for high-strength joints.
Fabrication techniques include cold forming, hot forging, and machining. Preheating to 300°F (149°C) is recommended to prevent cracking during forming. Post-weld annealing enhances weld integrity.
