Product Description

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

• Primary Elements: Nickel (Ni: 58-62%), Chromium (Cr: 20-23%), Molybdenum (Mo: 8-10%), Niobium (Nb: 3.15-4.15%) 
• Impurities: Low iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%) to minimize cracking risks 

2. Mechanical Properties

• Tensile Strength: ≥760 MPa .
• Yield Strength: ≥420 MPa .
• Elongation: ≥27%
• Impact Toughness: High resistance to fatigue and stress corrosion cracking, suitable for cryogenic to high-temperature applications.

3. Physical Properties

• Density: 8.4 g/cm³ .
• Melting Range: 1290-1350°C .
• Structure: Face-centered cubic lattice, transitioning to stable Ni3(Nb,Ti) phases after heat treatment at ~650°C.

4. Key Features

• Corrosion Resistance: Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride, acidic, and marine environments .
• High-Temperature Stability: Maintains strength and oxidation resistance up to 1800°F (982°C) .
• Versatility: Suitable for welding dissimilar metals (e.g., carbon steel to nickel alloys) and surface cladding .

5. Welding Process Compatibility

• Methods: Compatible with TIG (GTAW), MIG (GMAW), submerged arc (SAW), and plasma arc welding 
• Shielding Gas: Argon or argon-helium mixtures for TIG/MIG; INCOFLUX 7 flux recommended for SAW .
• Wire Diameters: 0.8-3.2 mm (spooled or straight rods).

6. Applications

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

7. Standards & Certifications

• AWS/ASME: Compliant with AWS A5.14, ASME SFA-5.14, and UNS N06625 .
• Certifications: ABS, NADCAP, and ISO 18274 for critical industries.

8. Handling & Storage

• Moisture Control: Store in dry conditions; copper-coated variants improve conductivity.
• Pre-Weld Prep: Clean surfaces of oil, rust, and moisture; use low heat input to avoid embrittlement .

9. Packaging & Availability

• Packaging: Spools (5-15 kg) or straight rods.
• Lead Time: Typically ships within 3-15 days, depending on quantity.

Summary: ERNiCrMo-3 is a premium welding wire tailored for extreme environments, combining robust mechanical properties, corrosion resistance, and adaptability across industries.
