Crafted to perfection, ERNiCrMo-3 (AWS A5.14) is a nickel-chromium-molybdenum alloy with meticulous elemental control, ensuring unmatched performance and reliability.

• Primary Elements: Nickel (Ni: 58-62%), Chromium (Cr: 20-23%), Molybdenum (Mo: 8-10%), Niobium (Nb: 3.15-4.15%) — delivering robust structural integrity.
• Impurities: Engineered to contain low levels of iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%) to effectively minimize risks of cracking and ensure durability.

2. Mechanical Properties

• Tensile Strength: An impressive ≥760 MPa, ensuring exceptional load-bearing capacity.
• Yield Strength: A robust ≥420 MPa, providing reliable resistance to deformation.
• Elongation: A significant ≥27%, allowing for flexibility and adaptability in various applications.
• Impact Toughness: Demonstrates high resistance to fatigue and stress corrosion cracking, making it ideal for environments ranging from cryogenic to high-temperature.

3. Physical Properties

• Density: Precisely 8.4 g/cm³, reflecting its solid construction.
• Melting Range: A broad range of 1290-1350°C, ensuring versatility in high-temperature applications.
• Structure: Features a face-centered cubic lattice, transforming into stable Ni3(Nb,Ti) phases post heat treatment at ~650°C, enhancing resilience.

4. Key Features

• Corrosion Resistance: Offers outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich, acidic, and marine environments, safeguarding your investments.
• High-Temperature Stability: Retains superior strength and oxidation resistance even at soaring temperatures up to 1800°F (982°C), ensuring persistent performance.
• Versatility: Ideally suited for welding dissimilar metals, including carbon steel to nickel alloys, and perfect for surface cladding applications.

5. Welding Process Compatibility

• Methods: Compatible with a range of welding methods including TIG (GTAW), MIG (GMAW), submerged arc (SAW), and plasma arc welding, offering flexibility and efficiency.
• Shielding Gas: Utilize argon or argon-helium mixtures for TIG/MIG; INCOFLUX 7 flux is recommended for SAW to enhance weld quality.
• Wire Diameters: Available in versatile sizes from 0.8-3.2 mm, either spooled or as straight rods, catering to diverse application needs.

6. Applications

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

7. Standards & Certifications

• AWS/ASME: Fully compliant with AWS A5.14, ASME SFA-5.14, and UNS N06625, meeting rigorous industry standards.
• Certifications: Certified by ABS, NADCAP, and ISO 18274 for use in critical industries, ensuring quality and reliability.

8. Handling & Storage

• Moisture Control: Ensure optimal performance by storing in dry conditions. The copper-coated variants are designed to enhance electrical conductivity, making them a superior choice for efficient welding.
• Pre-Weld Prep: Prior to welding, meticulously clean surfaces to remove oil, rust, and moisture. Employ low heat input to prevent embrittlement and ensure the integrity of the weld.

9. Packaging & Availability

• Packaging: Available in practical formats—choose between spools ranging from 5 to 15 kg or straight rods, tailored for convenience and efficiency in your projects.
• Lead Time: With a commitment to prompt service, we typically ship within 3 to 15 days, accommodating specific quantity needs to ensure your projects stay on schedule.

Summary: ERNiCrMo-3 is a cutting-edge welding wire engineered for the most demanding environments. It offers exceptional mechanical properties and superior corrosion resistance, making it versatile and indispensable across various industries.
