• Impurities: Features minimal iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%) content to significantly reduce cracking risks and enhance durability.

2. Mechanical Properties

• Tensile Strength: ≥760 MPa, demonstrating extraordinary tensile capabilities.
• Yield Strength: ≥420 MPa, ensuring robust performance under load.
• Elongation: ≥27%, offering exceptional flexibility and resilience.
• Impact Toughness: Provides high resistance to fatigue and stress corrosion cracking, making it ideal for applications spanning cryogenic to high-temperature environments.

3. Physical Properties

• Density: 8.4 g/cm³, ensuring a dense, durable structure.
• Melting Range: 1290-1350°C, offering stability across a range of temperatures.
• Structure: Face-centered cubic lattice, which transitions to stable Ni3(Nb,Ti) phases after heat treatment at approximately 650°C, ensuring stability and strength.

4. Key Features

• Corrosion Resistance: Exhibits excellent resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride, acidic, and marine environments, safeguarding your projects against harsh conditions.
• High-Temperature Stability: Maintains impressive strength and oxidation resistance up to 1800°F (982°C), ensuring reliability in high-temperature applications.
• Versatility: Versatile for welding dissimilar metals, such as carbon steel to nickel alloys, and effective for surface cladding, providing flexibility in various applications.

5. Welding Process Compatibility

• Methods: Compatible with multiple welding methods including TIG (GTAW), MIG (GMAW), submerged arc (SAW), and plasma arc welding, enhancing adaptability in any project.
• Shielding Gas: Utilizes argon or argon-helium mixtures for TIG/MIG; with INCOFLUX 7 flux recommended for SAW, optimizing welding quality and performance.
• Wire Diameters: Available in a range of 0.8-3.2 mm (spooled or straight rods), offering options for different welding needs.

6. Applications

• Industries: Ideal for aerospace (engine components, exhaust systems), chemical processing (reactors, pipelines), marine (valves, seawater systems), and oil/gas (wellhead equipment), broadening your industry reach.
• Materials Welded: Perfect for welding INCONEL 625, INCOLOY 825, 20alloy, 9% Ni steel, and dissimilar combinations, like nickel alloys to stainless steel, demonstrating material compatibility.
