1. Chemical Composition
ERNiCrMo-3 (AWS A5.14) is a premium nickel-chromium-molybdenum alloy meticulously crafted with precise elemental control, ensuring unparalleled performance:

• Primary Elements: Nickel (Ni: 58-62%), Chromium (Cr: 20-23%), Molybdenum (Mo: 8-10%), Niobium (Nb: 3.15-4.15%)
• Impurities: Contains minimal impurities with low iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%) to significantly reduce the risk of cracking.

2. Mechanical Properties

• Tensile Strength: ≥760 MPa, showcasing remarkable strength.
• Yield Strength: ≥420 MPa, ensuring robust performance.
• Elongation: ≥27% elongation, offering excellent flexibility and adaptability.
• Impact Toughness: Exhibits exceptional resistance to fatigue and stress corrosion cracking, making it ideal for conditions ranging from cryogenic to high-temperature applications.

3. Physical Properties

• Density: 8.4 g/cm³, providing a stable structural foundation.
• Melting Range: 1290-1350°C, allowing for a broad operational temperature range.
• Structure: Features a face-centered cubic lattice, transitioning to stable Ni3(Nb,Ti) phases after heat treatment around 650°C, ensuring lasting durability.

4. Key Features

• Corrosion Resistance: Offers outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, even in harsh chloride, acidic, and marine environments.
• High-Temperature Stability: Maintains impressive strength and oxidation resistance up to 1800°F (982°C), ensuring reliability in high-temperature applications.
• Versatility: Ideal for welding dissimilar metals, such as carbon steel to nickel alloys, and for surface cladding, demonstrating remarkable adaptability.

5. Welding Process Compatibility

• Methods: Perfectly compatible with various welding methods including TIG (GTAW), MIG (GMAW), submerged arc (SAW), and plasma arc welding, enhancing its utility.
• Shielding Gas: Utilizes argon or argon-helium mixtures for TIG/MIG; INCOFLUX 7 flux recommended for SAW, optimizing welding performance.
• Wire Diameters: Available in 0.8-3.2 mm diameters, provided as spooled or straight rods to suit various welding needs.

6. Applications

• Industries: Extensively used in aerospace (engine components, exhaust systems), chemical processing (reactors, pipelines), marine (valves, seawater systems), and oil/gas (wellhead equipment) industries, showcasing its broad applicability.
• Materials Welded: Suitable for welding materials like INCONEL 625, INCOLOY 825, 20alloy, 9% Ni steel, and a variety of dissimilar combinations such as nickel alloys to stainless steel.

7. Standards & Certifications
