Chemical Composition
| Element | Content Range (%) | Function |
|---|---|---|
| Nickel (Ni) | ≥ 57 | Base metal; provides structural stability and resistance to chloride stress corrosion cracking |
| Molybdenum (Mo) | 15.0 - 17.0 | Enhances resistance to pitting, crevice corrosion, and reducing acids |
| Chromium (Cr) | 14.5 - 16.5 | Improves oxidation resistance and resistance to oxidizing acids |
| Iron (Fe) | 4.0 - 7.0 | Optimizes mechanical properties and processability |
| Tungsten (W) | 3.0 - 4.5 | Boosts pitting corrosion resistance in chloride-rich environments |
| Cobalt (Co) | ≤ 2.5 | Controls alloy stability and minimizes intermetallic phase formation |
| Carbon (C) | ≤ 0.01 | Reduces carbide precipitation, preventing intergranular corrosion |
| Silicon (Si) | ≤ 0.08 | Limits oxide formation and improves casting quality |
| Manganese (Mn) | ≤ 1.0 | Aids in deoxidation during manufacturing |

Corrosion Resistance
- Chloride Environments: Resists pitting, crevice corrosion, and stress corrosion cracking in seawater, brines, and chloride-based solvents
- Acid Resistance: Performs well in both oxidizing and reducing acids including sulfuric acid and mixed acids
- Oxidation & Sulfidation: Withstands continuous exposure to high temperatures without significant scaling; resistant to sulfur-containing gases
- Low-Temperature Stability: No embrittlement at cryogenic temperatures down to -269°C, suitable for LNG equipment
Applications
- Petrochemical & Refining: Manifolds, valve stems, pump shafts, and reactor internals
- Chemical Processing: Heat exchanger tubesheets, agitator shafts, and storage tank nozzles
- Marine & Offshore: Propeller shafts, seawater cooling system components, and subsea pipeline connectors
- Power Generation: Boiler tubes, turbine blades, and flue gas desulfurization systems
- Aerospace & Defense: Engine components and rocket fuel lines
- Pharmaceutical & Food Processing: Equipment shafts and mixing blades
