ERNiCrMo-3 Nickel Alloy Welding Wire
1. Chemical Composition
ERNiCrMo-3 (AWS A5.14) is a superbly engineered nickel-chromium-molybdenum alloy, meticulously crafted with precise elemental control to deliver exceptional performance:
- Primary Elements: Featuring Nickel (Ni: 58-62%), Chromium (Cr: 20-23%), Molybdenum (Mo: 8-10%), and Niobium (Nb: 3.15-4.15%) for superior quality
- Impurities: Contains minimal levels of iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%) to significantly reduce the risk of cracking
2. Mechanical Properties
- Tensile Strength: An impressive ≥760 MPa, ensuring robust durability.
- Yield Strength: At least ≥420 MPa, providing excellent support under stress.
- Elongation: Remarkable elongation of ≥27%, offering flexibility and resilience.
- Impact Toughness: High resistance to fatigue and stress corrosion cracking, perfectly suited for applications ranging from cryogenic to high temperatures.
3. Physical Properties
- Density: Boasts a density of 8.4 g/cm³, providing strength and stability.
- Melting Range: Withstands temperatures from 1290-1350°C, offering reliable melting stability.
- Structure: Features a face-centered cubic lattice that transitions to stable Ni3(Nb,Ti) phases following heat treatment at approximately 650°C.
4. Key Features
- Corrosion Resistance: Offers unparalleled resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-rich, acidic, and marine settings.
- High-Temperature Stability: Maintains impeccable strength and oxidation resistance even at soaring temperatures up to 1800°F (982°C).
- Versatility: Exceptionally versatile, making it ideal for welding dissimilar metals like carbon steel to nickel alloys, as well as for surface cladding.
5. Welding Process Compatibility
- Methods: Broad compatibility with TIG (GTAW), MIG (GMAW), submerged arc (SAW), and plasma arc welding for diverse applications.
- Shielding Gas: Utilizes argon or argon-helium mixes for TIG/MIG; INCOFLUX 7 flux is recommended for SAW, enhancing weld quality.
- Wire Diameters: Available in diameters ranging from 0.8-3.2 mm, offered in both spooled and straight rod formats.
6. Applications
- Industries: Widely used across aerospace (engine components, exhaust systems), chemical processing (reactors, pipelines), marine (valves, seawater systems), and oil/gas (wellhead equipment) sectors.
- Materials Welded: Perfect for welding INCONEL 625, INCOLOY 825, 20alloy, 9% Ni steel, and in creating dissimilar combinations like nickel alloys to stainless steel.
7. Standards & Certifications
- AWS/ASME: Fully compliant with AWS A5.14, ASME SFA-5.14, and UNS N06625 standards, ensuring quality and reliability.
- Certifications: Accredited with ABS, NADCAP, and ISO 18274 certifications, meeting the stringent demands of critical industries.
8. Handling & Storage
- Moisture Control: Ensure optimal efficiency by storing the product in dry conditions. Enhance performance with copper-coated variants that significantly improve conductivity.
- Pre-Weld Preparation: Achieve perfect welds by meticulously cleaning surfaces of oil, rust, and moisture. Employ low heat input to effectively prevent embrittlement and ensure superior weld integrity.
9. Packaging & Availability
- Packaging Options: Available in versatile packaging including spools ranging from 5-15 kg or as straight rods, tailored to your specific project needs.
- Lead Time: Expedient delivery assured, typically shipping within 3-15 days based on order quantity, ensuring your projects stay on schedule.
Summary: ERNiCrMo-3 is a top-tier welding wire engineered for the most demanding environments. It offers exceptional mechanical properties, unparalleled corrosion resistance, and versatile adaptability across multiple industries.
