• Impurities: Engineered with minimal impurities, featuring low iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%) to significantly reduce cracking risks.

2. Mechanical Properties

• Tensile Strength: Demonstrates remarkable tensile strength of ≥760 MPa, ensuring robust performance.
• Yield Strength: Delivers an impressive yield strength of ≥420 MPa, providing reliability under stress.
• Elongation: Exhibits excellent elongation of ≥27%, enhancing flexibility and durability.
• Impact Toughness: Offers superior impact toughness with high resistance to fatigue and stress corrosion cracking, making it ideal for both cryogenic and high-temperature environments.

3. Physical Properties

• Density: Features a robust density of 8.4 g/cm³, contributing to its strength.
• Melting Range: Possesses a versatile melting range of 1290-1350°C, suitable for various industrial applications.
• Structure: Displays a face-centered cubic lattice, transitioning to stable Ni3(Nb,Ti) phases post heat treatment at approximately 650°C, ensuring structural integrity.

4. Key Features

• Corrosion Resistance: Boasts outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, proving indispensable in chloride, acidic, and marine environments.
• High-Temperature Stability: Retains formidable strength and oxidation resistance up to 1800°F (982°C), making it suitable for high-temperature applications.
• Versatility: Exceptionally versatile, ideal for welding dissimilar metals such as carbon steel to nickel alloys and for surface cladding.

5. Welding Process Compatibility

• Methods: Seamlessly compatible with TIG (GTAW), MIG (GMAW), submerged arc (SAW), and plasma arc welding techniques.
• Shielding Gas: Optimal performance achieved with argon or argon-helium mixtures for TIG/MIG; INCOFLUX 7 flux is recommended for SAW processes.
• Wire Diameters: Available in diameters ranging from 0.8-3.2 mm, offered in both spooled and straight rod formats.

6. Applications

• Industries: Widely used across aerospace (engine components, exhaust systems), chemical processing (reactors, pipelines), marine (valves, seawater systems), and oil/gas sectors (wellhead equipment).
• Materials Welded: Expertly welds materials such as INCONEL 625, INCOLOY 825, 20alloy, 9% Ni steel, and various dissimilar combinations, including nickel alloys to stainless steel.
