- Minimal Impurities: Featuring low iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%) to substantially reduce cracking risks, enhancing longevity and reliability.
2. Superior Mechanical Properties
- Tensile Strength: ≥760 MPa - Exceeding industry standards for robust applications.
- Yield Strength: ≥420 MPa - Ensuring steadfast performance across demanding conditions.
- Elongation: ≥27% - Demonstrates remarkable ductility and flexibility.
- Impact Toughness: Exhibits outstanding resistance to fatigue and stress corrosion cracking, making it ideal for use from cryogenic to high-temperature environments.
3. Intriguing Physical Properties
- Density: 8.4 g/cm³ - Optimal density for versatile applications.
- Melting Range: 1290-1350°C - Withstands intense heat, broadening its application scope.
- Structural Integrity: Exhibits a face-centered cubic lattice, evolving into stable Ni3(Nb,Ti) phases post heat treatment at ~650°C, ensuring durability.
4. Distinctive Key Features
- Unmatched Corrosion Resistance: Exceptional protection against pitting, crevice corrosion, and stress corrosion cracking in harsh chloride, acidic, and marine environments.
- Remarkable High-Temperature Stability: Retains its strength and resists oxidation up to 1800°F (982°C), showcasing its superiority in extreme conditions.
- Unparalleled Versatility: Apt for welding dissimilar metals like carbon steel to nickel alloys and surface cladding, enhancing its application range.
5. Seamless Welding Process Compatibility
- Versatile Methods: Perfectly compatible with TIG (GTAW), MIG (GMAW), submerged arc (SAW), and plasma arc welding techniques.
- Optimal Shielding Gas: Utilize Argon or argon-helium mixtures for TIG/MIG; INCOFLUX 7 flux is recommended for SAW to enhance weld quality.
- Diverse Wire Diameters: Available in 0.8-3.2 mm (spooled or straight rods), catering to varied project needs.
6. Broad Applications
- Versatile Industries: Serves aerospace (engine components, exhaust systems), chemical processing (reactors, pipelines), marine (valves, seawater systems), and oil/gas (wellhead equipment).
- Diverse Materials Welded: Efficiently welds INCONEL 625, INCOLOY 825, 20alloy, 9% Ni steel, and dissimilar combinations like nickel alloys to stainless steel.
7. Rigorous Standards & Certifications
