Product Description

ERNiCrMo-3 Nickel Alloy Welding Wire: A Premium Choice for Demanding Conditions
1. Chemical Composition: The Building Blocks of Excellence
ERNiCrMo-3 (AWS A5.14) is expertly formulated as a nickel-chromium-molybdenum alloy, where each element is meticulously controlled to promise outstanding performance:

• Primary Elements That Define Quality: Nickel (Ni: 58-62%), Chromium (Cr: 20-23%), Molybdenum (Mo: 8-10%), Niobium (Nb: 3.15-4.15%) - A harmonious blend for superior strength.
• Managing Impurities for Optimal Functionality: Impeccably low levels of iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%) are maintained to significantly reduce the risk of cracks.

2. Mechanical Properties: Built for Performance

• Tensile Strength - Staying Power: ≥760 MPa - Engineered to withstand immense pressure.
• Yield Strength - Resilience under Stress: ≥420 MPa - Ensuring durability even in challenging conditions.
• Elongation - Flexibility and Endurance: ≥27% - Designed to stretch and recover.
• Impact Toughness - Standing Strong: Extraordinary resistance against fatigue and stress corrosion cracking, adaptable from cryogenic to high-temperature settings.

3. Physical Properties: Grounded in Precision

• Density - The Core of Balance: 8.4 g/cm³ - Reflects the compact yet robust nature of the alloy.
• Melting Range - Versatile Heat Performance: 1290-1350°C - Accommodates a wide range of heat applications.
• Structure - The Framework of Excellence: Features a face-centered cubic lattice structure, transforming into stable Ni3(Nb,Ti) phases post heat treatment at approximately 650°C.

4. Key Features: Unmatched Characteristics

• Corrosion Resistance - Unyielding Defense: Exceptional resistance to pitting, crevice, and stress corrosion cracking in corrosive environments including chloride, acidic, and marine settings.
• High-Temperature Stability - Consistency at Extreme Temperatures: Retains strength and resists oxidation superbly up to 1800°F (982°C).
• Versatility - Adaptability Across Applications: Perfect for welding dissimilar metals such as carbon steel to nickel alloys, and for surface cladding operations.

5. Welding Process Compatibility: Flexibility for All Techniques

• Methods - Embracing Diverse Welding Approaches: Seamlessly compatible with TIG (GTAW), MIG (GMAW), submerged arc (SAW), and plasma arc welding processes.
• Shielding Gas Options - Protecting Every Weld: Use argon or argon-helium mixtures for TIG/MIG; INCOFLUX 7 flux recommended for SAW to ensure optimal protection.
• Wire Diameters - Customization for Precision: Offered in 0.8-3.2 mm sizes, available as spooled or straight rods to meet diverse application needs.

6. Applications: Catering to Industry Giants

• Industries - Powering Progress in Key Sectors: Tailored for aerospace (engine components, exhaust systems), chemical processing (reactors, pipelines), marine (valves, seawater systems), and oil/gas (wellhead equipment).
• Materials Welded - Bridging Metal Differences: Efficiently welds INCONEL 625, INCOLOY 825, 20alloy, 9% Ni steel, and dissimilar combinations such as nickel alloys to stainless steel.

7. Standards & Certifications: Assurance of Quality

• AWS/ASME Compliance - Rigorous Standards Met: Fully compliant with AWS A5.14, ASME SFA-5.14, and UNS N06625 standards.
• Certifications - Trust in Proven Excellence: Attained ABS, NADCAP, and ISO 18274 certifications, ensuring reliability in critical industries.

8. Handling & Storage: Preserving Quality

• Moisture Control - Guarding Against Deterioration: Ensure optimal results by storing in dry, moisture-free conditions. Our copper-coated variants significantly enhance conductivity, providing you with superior performance.
• Pre-Weld Prep: Prior to welding, meticulously clean all surfaces to remove any oil, rust, and moisture. Employ low heat input to prevent embrittlement, ensuring a flawless welding process.

9. Packaging & Availability

• Packaging: Available in convenient spools ranging from 5 to 15 kg or as straight rods, offering flexibility for your specific needs.
• Lead Time: Our products typically ship within a swift timeframe of 3 to 15 days, tailored to meet your order quantity requirements.

Summary: Discover the unparalleled excellence of ERNiCrMo-3, a premium welding wire engineered for the most demanding environments. It boasts exceptional mechanical properties, outstanding corrosion resistance, and remarkable versatility, making it the go-to choice across diverse industries.
