Chemical Composition
Main Elements
- Nickel (Ni): Minimum 58% - Provides excellent corrosion resistance in reducing environments and contributes to high-temperature strength and toughness
- Chromium (Cr): 20.0-23.0% - Forms protective chromium-oxide film for outstanding oxidation resistance at high temperatures
- Molybdenum (Mo): 8.0-10.0% - Enhances resistance to pitting and crevice corrosion in chloride-containing environments
- Niobium (Nb) + Tantalum (Ta): 3.15-4.15% - Provides precipitation strengthening through fine carbide formation
Minor Elements
- Carbon (C): Max 0.10% - Limited to prevent carbide formation and maintain corrosion resistance
- Silicon (Si): Max 0.50% - Aids in deoxidation during production
- Manganese (Mn): Max 0.50% - Supports deoxidation process
- Phosphorus (P): Max 0.015% - Controlled to prevent reduced ductility
- Sulfur (S): Max 0.015% - Limited to avoid hot cracking susceptibility
