Product Description

ERNiCrMo-3 Nickel Alloy Welding Wire
Product Introduction
1. Chemical Composition
ERNiCrMo-3 (AWS A5.14) is a superior nickel-chromium-molybdenum alloy meticulously crafted for exceptional performance through precise elemental control:

  • Primary Elements: Nickel (Ni: 58-62%), Chromium (Cr: 20-23%), Molybdenum (Mo: 8-10%), Niobium (Nb: 3.15-4.15%)
  • Impurities: Contains low levels of iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%) to significantly reduce the risk of cracking.
  • Element  content (wt%)
    Nickel (Ni)   ≥58.0
    Chromium (Cr)  20.0-23.0
    Iron (Fe)  5.00
    Manganese (Mn) 5.00
    Silicon (Si)  0.50
    Carbon (C)  0.10
    Copper (Cu)  0.50
    Molybdenum (Mo)  8.0-10.0
    Aluminum (Al)  0.4
    Titanium (Ti)  0.4
2. Mechanical Properties
  • Tensile Strength: ≥760 MPa. This ensures robust performance under extreme conditions.
  • Yield Strength: ≥420 MPa. Provides reliable resistance against deformation.
  • Elongation: ≥27%. Offers flexibility and resilience.
  • Impact Toughness: Exhibits high resistance to fatigue and stress corrosion cracking, making it ideal for applications ranging from cryogenic to high-temperature environments.
3. Physical Properties
  • Density: 8.4 g/cm³. Ensures material integrity under various conditions.
  • Melting Range: 1290-1350°C. Consistent performance within a wide thermal range.
  • Structure: Features a face-centered cubic lattice, transitioning to stable Ni3(Nb,Ti) phases after heat treatment at approximately 650°C for enhanced durability.
4. Key Features
  • Corrosion Resistance: Boasts excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride, acidic, and marine environments.
  • High-Temperature Stability: Retains strength and oxidation resistance up to 1800°F (982°C), ensuring reliable performance at elevated temperatures.
  • Versatility: Ideal for welding dissimilar metals such as carbon steel to nickel alloys and for surface cladding applications.
5. Welding Process Compatibility
  • Methods: Highly compatible with TIG (GTAW), MIG (GMAW), submerged arc (SAW), and plasma arc welding, offering flexibility for various industrial needs.
  • Shielding Gas: Use argon or argon-helium mixtures for TIG/MIG; INCOFLUX 7 flux is recommended for SAW to optimize welding quality.
  • Wire Diameters: Available in 0.8-3.2 mm sizes, offered as spooled or straight rods for tailored application requirements.
6. Applications
  • Industries: Widely used in aerospace (engine components, exhaust systems), chemical processing (reactors, pipelines), marine (valves, seawater systems), and oil/gas (wellhead equipment) sectors for its exceptional qualities.
  • Materials Welded: Excellent for welding INCONEL 625, INCOLOY 825, 20alloy, 9% Ni steel, and various dissimilar combinations such as nickel alloys to stainless steel.
7. Standards & Certifications
