Product Description

ERNiCrMo-3 Nickel Alloy Welding Wire
1. Chemical Composition
ERNiCrMo-3 (AWS A5.14) is a premium nickel-chromium-molybdenum alloy, expertly formulated with precise elemental control to ensure outstanding performance:

• Primary Elements: Nickel (Ni: 58-62%), Chromium (Cr: 20-23%), Molybdenum (Mo: 8-10%), Niobium (Nb: 3.15-4.15%)
• Impurities: With meticulously low levels of iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%), the alloy significantly reduces the risk of cracking, ensuring longevity and durability.

2. Mechanical Properties

• Tensile Strength: ≥760 MPa, demonstrating exceptional resilience under stress.
• Yield Strength: ≥420 MPa, offering robust endurance and stability in challenging conditions.
• Elongation: ≥27%, providing crucial flexibility and adaptability.
• Impact Toughness: This alloy exhibits superior resistance to fatigue and stress corrosion cracking, perfectly suited for both cryogenic and high-temperature applications.

3. Physical Properties

• Density: 8.4 g/cm³, a testament to its substantial structural integrity.
• Melting Range: 1290-1350°C, ensuring stability in extreme thermal environments.
• Structure: The alloy features a face-centered cubic lattice, transitioning into stable Ni3(Nb,Ti) phases following heat treatment at approximately 650°C, enhancing its robustness.

4. Key Features

• Corrosion Resistance: Possessing unparalleled resistance to pitting, crevice corrosion, and stress corrosion in environments laden with chlorides, acids, and marine conditions.
• High-Temperature Stability: Retains formidable strength and oxidation resistance up to 1800°F (982°C), perfect for demanding high-temperature applications.
• Versatility: Ideally suited for welding dissimilar metals, such as carbon steel to nickel alloys and for surface cladding, offering unmatched utility.

5. Welding Process Compatibility

• Methods: Compatible with TIG (GTAW), MIG (GMAW), submerged arc (SAW), and plasma arc welding, ensuring flexibility in fabrication processes.
• Shielding Gas: Utilize argon or argon-helium mixtures for TIG/MIG; INCOFLUX 7 flux is recommended for SAW to guarantee optimal welding conditions.
• Wire Diameters: Available in sizes ranging from 0.8-3.2 mm, whether spooled or in straight rods, providing versatile application possibilities.

6. Applications

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

7. Standards & Certifications

• AWS/ASME: Fully compliant with AWS A5.14, ASME SFA-5.14, and UNS N06625, ensuring top-tier reliability and safety.
• Certifications: Accredited by ABS, NADCAP, and ISO 18274, guaranteeing adherence to the highest standards for critical industry applications.

8. Handling & Storage

• Moisture Control: For optimal performance, ensure storage in dry conditions. Our copper-coated variants significantly enhance conductivity.
• Pre-Weld Preparation: Thoroughly clean surfaces to remove oil, rust, and moisture. Employ low heat inputs to prevent embrittlement, ensuring superior weld integrity.

9. Packaging & Availability

• Packaging: Available in convenient spools ranging from 5-15 kg or as straight rods to suit diverse fabrication needs.
• Lead Time: Orders typically ship within 3-15 days, contingent upon requested quantities, ensuring timely delivery.

Summary: The ERNiCrMo-3 Nickel Alloy Wire stands as a superior welding solution for challenging environments, offering an exceptional blend of mechanical strength, corrosion resistance, and versatility across a multitude of industries.
