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.
