- Machinability: Requires specialized tools due to hardness.
Corrosion Data for Stellite1 Cobalt Alloy Tube
| Environment | Corrosion Rate (mm/year) |
|---|---|
| Atmospheric (Urban) | <0.01 |
| Seawater | 0.02-0.05 |
| Mild Sulfuric Acid (10%) | 0.1-0.3 |
Best Welding and Manufacturing Practices
Recommended welding methods for Stellite1 Cobalt Alloy Tubes include TIG (Tungsten Inert Gas) and plasma arc welding. Preheating to 200-300°C is advised to minimize cracking. Forming techniques such as bending and cutting require high-precision tools due to the material’s hardness. Annealing may be applied post-fabrication to relieve stresses.
