ERCOKRA is a cobalt-based filler metal conforming to AWS A5.21 specifications. Its composition includes:
| Cobalt (Co) | 50.0 – 60.0% + up to 2.5% |
| Chromium (Cr) | 20.0 – 22.5% |
| Molybdenum (Mo) | 12.5 – 16.0% |
| Tungsten (W) | ~4% |
| Iron (Fe) | 2.0 – 6.0% |
| Carbon (C) | Max 0.015% |
| Copper (Cu) | Max 0.50% |
| Manganese (Mn) | Max 0.50% |
| Phosphorus (P) | Max 0.02% |
| Sulfur (S) | Max 0.01% |
| Silicon (Si) | Max 0.08% |
| Vanadium (V) | Max 0.35% |
Key Properties
