Product Description

ERNiCrMo-3 Nickel Alloy Welding Wire
1. Chemical Composition
ERNiCrMo-3 (AWS A5.14) is a high-performance nickel-chromium-molybdenum alloy, crafted with precision to deliver exceptional quality and performance for demanding applications:

• Primary Elements: Nickel (Ni: 58-62%), Chromium (Cr: 20-23%), Molybdenum (Mo: 8-10%), Niobium (Nb: 3.15-4.15%) - expertly balanced to ensure excellent durability and reliability.
• Impurities: With minimal iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%), the risk of cracking is significantly reduced, ensuring robustness in every weld.

2. Mechanical Properties

• Tensile Strength: ≥760 MPa - Offering superior strength to endure high-stress environments.
• Yield Strength: ≥420 MPa - Ensuring resilience and reliability under load.
• Elongation: ≥27% - Demonstrates remarkable flexibility and adaptability.
• Impact Toughness: Exhibiting high resistance to fatigue and stress corrosion, this alloy is perfect for applications ranging from cryogenic to scorching high temperatures.

3. Physical Properties

• Density: 8.4 g/cm³ - A testament to the metal's dense and robust nature.
• Melting Range: 1290-1350°C - Offers a broad range, suitable for various high-temperature processes.
• Structure: Featuring a face-centered cubic lattice, this structure transitions to stable Ni3(Nb,Ti) phases after heat treatment at ~650°C, enhancing durability.

4. Key Features

• Corrosion Resistance: This alloy excels with unparalleled resistance to pitting, crevice corrosion, and stress corrosion cracking, even in the harshest chloride, acidic, and marine environments.
• High-Temperature Stability: It retains remarkable strength and oxidation resistance, even under temperatures soaring up to 1800°F (982°C).
• Versatility: Ideal for welding dissimilar metals, such as carbon steel to nickel alloys, and for surface cladding applications, making it an all-around solution.

5. Welding Process Compatibility

• Methods: Perfectly compatible with TIG (GTAW), MIG (GMAW), submerged arc (SAW), and plasma arc welding methods.
• Shielding Gas: Utilize argon or argon-helium mixtures for TIG/MIG; for SAW, use INCOFLUX 7 flux for optimal results.
• Wire Diameters: Available in diameters of 0.8-3.2 mm, provided as spooled or straight rods to suit all your welding needs.

6. Applications

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

7. Standards & Certifications

• AWS/ASME: Compliant with the rigorous standards of AWS A5.14, ASME SFA-5.14, and UNS N06625, ensuring top-tier quality and assurance.
• Certifications: Accredited by ABS, NADCAP, and ISO 18274, making it a trusted choice for critical industries demanding the highest level of reliability.

8. Handling & Storage

• Moisture Control: Ensure to store our premium ERNiCrMo-3 Nickel Alloy Welding Wire in impeccably dry conditions. The copper-coated variants not only enhance storage but also significantly improve conductivity.
• Pre-Weld Prep: Thoroughly clean all surfaces from oil, rust, and moisture. Utilize low heat input to preserve the material's integrity and prevent embrittlement.

9. Packaging & Availability

• Packaging: Available in convenient spools ranging from 5 to 15 kg or as straight rods, meeting diverse operational needs with flexibility.
• Lead Time: Our efficient logistics ensure shipping within 3 to 15 days, subject to order quantity, to meet your project timelines effectively.

Summary: The ERNiCrMo-3 Nickel Alloy Welding Wire is a superior choice for demanding environments. It seamlessly combines exceptional mechanical strength, unparalleled corrosion resistance, and versatility across a multitude of industries.
