ERNiCrMo-3 Nickel Alloy Welding Wire
1. Chemical Composition
ERNiCrMo-3 (AWS A5.14) is a nickel-chromium-molybdenum alloy crafted with meticulous elemental precision, ensuring outstanding performance:
- Primary Elements: Nickel (Ni: 58-62%), Chromium (Cr: 20-23%), Molybdenum (Mo: 8-10%), Niobium (Nb: 3.15-4.15%)
- Impurities: Ingeniously minimized impurities like iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%) substantially reduce cracking risks.
2. Mechanical Properties
- Tensile Strength: Uncompromising strength with a tensile threshold of ≥760 MPa.
- Yield Strength: Yielding a robust ≥420 MPa.
- Elongation: Demonstrates impressive ductility with ≥27% elongation.
- Impact Toughness: Exhibits exceptional resistance to fatigue and stress corrosion cracking, adaptable from cryogenic to elevated temperature environments.
3. Physical Properties
- Density: Impeccably dense at 8.4 g/cm³.
- Melting Range: A strategically broad melting span of 1290-1350°C.
- Structure: Characterized by a face-centered cubic lattice, transitioning to stable Ni3(Nb,Ti) phases post heat treatment at ~650°C.
4. Key Features
- Corrosion Resistance: Offers unparalleled resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride, acidic, and harsh marine settings.
- High-Temperature Stability: Retains formidable strength and oxidation resistance, enduring temperatures up to 1800°F (982°C).
- Versatility: Perfectly crafted for welding dissimilar metals (e.g., carbon steel to nickel alloys) and adept surface cladding.
5. Welding Process Compatibility
- Methods: Seamlessly compatible with TIG (GTAW), MIG (GMAW), submerged arc (SAW), and plasma arc welding techniques.
- Shielding Gas: Utilizes argon or argon-helium mixtures for TIG/MIG, with INCOFLUX 7 flux as the optimal choice for SAW.
- Wire Diameters: Available in versatile diameters from 0.8-3.2 mm, offered in both spooled and straight rod formats.
6. Applications
- Industries: Widely implemented across 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 such as nickel alloys to stainless steel.
7. Standards & Certifications
- AWS/ASME: Fully compliant with AWS A5.14, ASME SFA-5.14, and UNS N06625 standards.
- Certifications: Backed by robust certifications including ABS, NADCAP, and ISO 18274, ensuring reliability in critical industries.
8. Handling & Storage
- Moisture Control: Ensure that our ERNiCrMo-3 nickel alloy welding wire is stored under strictly dry conditions to maintain its optimal performance. The copper-coated variants are specially designed to enhance conductivity, ensuring superior results in every application.
- Pre-Weld Prep: Prior to welding, meticulously clean all surfaces to remove oil, rust, and moisture. Employ low heat input to prevent embrittlement and maintain the integrity of the weld, ensuring a flawless finish every time.
9. Packaging & Availability
- Packaging: Available in versatile packaging options to suit your needs, including spools ranging from 5 to 15 kg and straight rods, ensuring convenient handling and application.
- Lead Time: Our efficient delivery system typically dispatches orders within 3 to 15 days, depending on the quantity required, guaranteeing that you receive your materials promptly and ready for use.
Summary: The ERNiCrMo-3 welding wire is a top-tier choice for demanding marine applications and beyond, engineered to deliver exceptional mechanical properties, unmatched corrosion resistance, and versatility across diverse industries, making it an ideal solution for your welding needs.
