Product Description

ERNiCrMo-3 Nickel Alloy Welding Wire
1. Chemical Composition
ERNiCrMo-3 (AWS A5.14) stands out as a precise nickel-chromium-molybdenum alloy, expertly engineered for superior performance through meticulous elemental control:

• Primary Elements: Nickel (Ni: 58-62%), Chromium (Cr: 20-23%), Molybdenum (Mo: 8-10%), Niobium (Nb: 3.15-4.15%) - creating a robust foundation for remarkable welding capabilities.
• Impurities: With stringent limits on iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%), the risk of cracking is minimized to ensure integrity.

2. Mechanical Properties

• Tensile Strength: ≥760 MPa, ensuring robust material performance under stress.
• Yield Strength: ≥420 MPa, providing reliable strength for demanding applications.
• Elongation: ≥27%, offering excellent ductility for a wide range of manufacturing processes.
• Impact Toughness: Boasting high resistance to fatigue and stress corrosion, it's perfectly suited for applications from cryogenic to high temperatures.

3. Physical Properties

• Density: 8.4 g/cm³, reflecting its solid structural consistency.
• Melting Range: 1290-1350°C, allowing for versatile thermal applications.
• Structure: Exhibits a face-centered cubic lattice, transitioning to stable Ni3(Nb,Ti) phases post heat treatment, optimizing performance at elevated temperatures.

4. Key Features

• Corrosion Resistance: Demonstrates superb resistance to pitting, crevice, and stress corrosion in chloride, acidic, and marine environments, ensuring longevity.
• High-Temperature Stability: Retains formidable strength and resists oxidation up to 1800°F (982°C), maintaining performance in extreme conditions.
• Versatility: Ideal for welding diverse metals, such as carbon steel to nickel alloys, and effective for surface cladding.

5. Welding Process Compatibility

• Methods: Seamlessly compatible with TIG (GTAW), MIG (GMAW), submerged arc (SAW), and plasma arc welding, offering wide application flexibility.
• Shielding Gas: Utilizes argon or argon-helium mixtures for TIG/MIG; INCOFLUX 7 flux is advised for SAW, optimizing weld quality.
• Wire Diameters: Available in diameters ranging from 0.8-3.2 mm, in spooled or straight rod forms, catering to specific welding requirements.

6. Applications

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

7. Standards & Certifications

• AWS/ASME: Fully compliant with AWS A5.14, ASME SFA-5.14, and UNS N06625 standards, ensuring top-notch reliability.
• Certifications: Certified by ABS, NADCAP, and ISO 18274, meeting the stringent demands of critical industries.

8. Handling & Storage

• Moisture Control: Ensure optimal storage by maintaining dry conditions to preserve quality; the copper-coated variants are specially designed to enhance conductivity, making them a superior choice for precision tasks.
• Pre-Weld Prep: Thoroughly clean surfaces to eliminate oil, rust, and moisture. Employ low heat input to minimize the risk of embrittlement and ensure a seamless welding process.

9. Packaging & Availability

• Packaging: Available in versatile formats such as spools ranging from 5 to 15 kg or as straight rods, catering to diverse welding needs.
• Lead Time: Orders typically dispatch within a timeframe of 3 to 15 days, tailored to the quantity ordered, ensuring prompt delivery for your project timelines.

Summary: ERNiCrMo-3 is a top-tier welding wire engineered for the most demanding environments. It offers a perfect blend of superior mechanical strength, outstanding corrosion resistance, and versatility, making it indispensable across various industries.
