Product Description

ERNiCrMo-3 Nickel Alloy Welding Wire
1. Chemical Composition
ERNiCrMo-3 (AWS A5.14) is a superior nickel-chromium-molybdenum alloy, crafted with meticulous elemental control to guarantee peak performance:

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

2. Mechanical Properties

• Tensile Strength: ≥760 MPa, ensuring robust structural integrity.
• Yield Strength: ≥420 MPa, providing excellent durability.
• Elongation: ≥27%, offering flexibility and resilience.
• Impact Toughness: Exhibits high resistance to fatigue and stress corrosion cracking, making it ideal for applications ranging from cryogenic to high temperatures.

3. Physical Properties

• Density: 8.4 g/cm³, indicative of its substantial build.
• Melting Range: 1290-1350°C, ensuring adaptability across diverse thermal conditions.
• Structure: Features a face-centered cubic lattice, transitioning to stable Ni3(Nb,Ti) phases after precise heat treatment at ~650°C.

4. Key Features

• Corrosion Resistance: Offers outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, thriving in chloride, acidic, and marine environments.
• High-Temperature Stability: Retains exceptional strength and oxidation resistance up to 1800°F (982°C), ensuring longevity.
• Versatility: Perfectly suited for welding diverse metals, like carbon steel to nickel alloys, and for surface cladding applications.

5. Welding Process Compatibility

• Methods: Seamlessly integrates with TIG (GTAW), MIG (GMAW), submerged arc (SAW), and plasma arc welding processes.
• Shielding Gas: Utilizes argon or argon-helium mixtures for TIG/MIG; INCOFLUX 7 flux is the choice for SAW.
• Wire Diameters: Available in 0.8-3.2 mm, offering both spooled and straight rod options.

6. Applications

• Industries: Widely used in aerospace (engine components, exhaust systems), chemical processing (reactors, pipelines), marine (valves, seawater systems), and oil/gas (wellhead equipment).
• Materials Welded: Ideal for welding INCONEL 625, INCOLOY 825, 20alloy, 9% Ni steel, and dissimilar combinations like nickel alloys to stainless steel.
