Chemical Properties
Hastelloy B2 Pipe offers unmatched resistance to hydrochloric acid, sulfuric acid, and other reducing media. It performs well in corrosion-resistant alloys applications but is not recommended for oxidizing environments, as it may corrode under such conditions.
Things to Note (Limitations)
- Not suitable for oxidizing media (e.g., nitric acid)
- Limited performance above 1000°C due to potential embrittlement
- Requires careful welding to avoid intergranular corrosion
Corrosion Data for Hastelloy B2 Pipe
| Environment | Corrosion Rate (mm/year) |
|---|---|
| 10% Hydrochloric Acid (Boiling) | 0.05 |
| 20% Sulfuric Acid (80°C) | 0.1 |
| Atmospheric Exposure | Negligible |
Welding and Manufacturing Tips
Hastelloy B2 Pipe supports welding via TIG, MIG, and shielded metal arc welding. Preheating is not required, but post-weld heat treatment may be necessary to prevent cracking. Forming techniques include bending and machining, with proper tooling to handle its high strength.
