Product Description

ERNiCrMo-3 Nickel Alloy Welding Wire - A Pinnacle of Precision and Performance
1. Chemical Composition - Meticulously Engineered for Excellence
ERNiCrMo-3 (AWS A5.14) is a premium nickel-chromium-molybdenum alloy, showcasing unmatched elemental precision for paramount performance:

• Primary Elements - The Cornerstone of Quality: Nickel (Ni: 58-62%), Chromium (Cr: 20-23%), Molybdenum (Mo: 8-10%), Niobium (Nb: 3.15-4.15%)
• Impurities - Minimized for Maximum Integrity: Low iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%) to significantly reduce cracking risks

2. Mechanical Properties - Robust and Reliable

• Tensile Strength - Built to Endure: ≥760 MPa, ensuring exceptional durability.
• Yield Strength - Power to Perform: ≥420 MPa, promising outstanding resistance to deformation.
• Elongation - Flexibility Defined: ≥27%, offering superior ductility.
• Impact Toughness - Resilient in Extremes: High resistance to fatigue and stress corrosion cracking, exceptionally suitable for cryogenic to high-temperature applications.

3. Physical Properties - Intrinsic Strengths

• Density - Solid Foundations: 8.4 g/cm³, providing a dense and stable composition.
• Melting Range - Temperature Versatility: 1290-1350°C, allowing extensive application versatility.
• Structure - Engineered for Stability: Face-centered cubic lattice, transitioning to robust Ni3(Nb,Ti) phases after heat treatment at approximately 650°C.

4. Key Features - Excellence in Every Aspect

• Corrosion Resistance - Unparalleled Protection: Exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking across chloride, acidic, and marine environments.
• High-Temperature Stability - Resilience Redefined: Sustains strength and resists oxidation up to 1800°F (982°C).
• Versatility - The Choice for Challenging Connections: Perfect for welding dissimilar metals (e.g., carbon steel to nickel alloys) and surface cladding.

5. Welding Process Compatibility - Adaptable and Efficient

• Methods - A Range of Compatibility: Seamlessly compatible with TIG (GTAW), MIG (GMAW), submerged arc (SAW), and plasma arc welding.
• Shielding Gas - Precision Protection: Utilizes Argon or argon-helium mixtures for TIG/MIG; INCOFLUX 7 flux is recommended for SAW.
• Wire Diameters - Tailored to Your Needs: Available in 0.8-3.2 mm, suitable for spooled or straight rod applications.

6. Applications - Versatility Across Industries

• Industries - Innovating Across Sectors: Serving aerospace (engine components, exhaust systems), chemical processing (reactors, pipelines), marine (valves, seawater systems), and oil/gas (wellhead equipment).
• Materials Welded - Connecting High-End Materials: Compatible with INCONEL 625, INCOLOY 825, 20alloy, 9% Ni steel, and dissimilar combinations such as nickel alloys to stainless steel.

7. Standards & Certifications - Trusted Quality Assurance

• AWS/ASME - Standards of Excellence: Fully compliant with AWS A5.14, ASME SFA-5.14, and UNS N06625 standards.
• Certifications - Elite Recognition: Proudly carries ABS, NADCAP, and ISO 18274 certifications for critical industry applications.

8. Handling & Storage

• Moisture Control: Ensure optimal storage by maintaining dry conditions to preserve quality; copper-coated variants are engineered to enhance electrical conductivity, making them an ideal choice for high-performance applications.
• Pre-Weld Prep: Achieve superior weld quality by meticulously cleaning surfaces of oil, rust, and moisture. Employ a controlled, low heat input to prevent embrittlement, ensuring the integrity and longevity of your welds.

9. Packaging & Availability

• Packaging: Choose from versatile packaging options: spools ranging from 5 to 15 kg or straight rods, designed for convenience and efficiency in handling and use.
• Lead Time: With a commitment to prompt delivery, most orders ship within 3 to 15 days, contingent on the quantity, ensuring your project timelines are always met.

Summary: ERNiCrMo-3 stands as the epitome of premium welding wires, specifically engineered to withstand the most extreme environments. It combines exceptional mechanical properties with unmatched corrosion resistance, offering unparalleled versatility across a multitude of industrial applications.
