Chemical Properties
The Stellite100 Cobalt Alloy Pipe offers excellent resistance to acids (e.g., sulfuric and hydrochloric) and alkalis, making it ideal for chemical processing. However, prolonged exposure to highly concentrated oxidizing acids may require additional coatings. This product complies with environmental regulations, but recycling is recommended due to cobalt content.
Things to Note (Limitations)
While the Stellite100 Cobalt Alloy Pipe is highly durable, note the following:
- High Temperatures: Performance may degrade above 1000°C in oxidizing environments.
- Brittleness: High hardness may lead to cracking under extreme mechanical shock.
- Cost: Higher cobalt alloy price compared to standard stainless steel due to premium materials.
Corrosion Data for Stellite100 Cobalt Alloy Pipe
| Environment | Corrosion Rate (mm/year) |
|---|---|
| Atmospheric (Urban) | <0.01 |
| Seawater | <0.02 |
| 10% Sulfuric Acid | 0.05-0.1 |
| 10% Hydrochloric Acid | 0.1-0.2 |
Best Welding and Manufacturing Practices
Recommended welding methods for Stellite100 Cobalt Alloy Pipe include:
- TIG Welding: Ensures precise welds with minimal distortion.
- Plasma Arc Welding: Suitable for high-quality joints.
- Shielded Metal Arc Welding: Effective for thicker sections.
Fabrication involves cold forming for thinner pipes and hot forming for thicker ones. Machining requires carbide tools due to the alloy’s hardness. Annealing may be needed post-fabrication to relieve stresses.
