1. Chemical Composition
ERNiCrMo-3 (AWS A5.14) is a meticulously engineered nickel-chromium-molybdenum alloy, offering superior performance with precise elemental control:
- Primary Elements: High-grade Nickel (Ni: 58-62%), resilient Chromium (Cr: 20-23%), robust Molybdenum (Mo: 8-10%), and durable Niobium (Nb: 3.15-4.15%)
- Impurities: Minimized impurities with low iron (Fe ≤1.0%), reduced sulfur (S ≤0.02%), and phosphorus (P ≤0.015%) to significantly lower cracking risks
2. Mechanical Properties
- Tensile Strength: Achieves a minimum of 760 MPa, ensuring strength and reliability.
- Yield Strength: Guarantees ≥420 MPa, providing extraordinary durability.
- Elongation: Delivers ≥27%, offering remarkable flexibility and resilience.
- Impact Toughness: Exhibits superior resistance to fatigue and stress corrosion cracking, perfect for both cryogenic and high-temperature applications.
3. Physical Properties
- Density: Precisely calculated at 8.4 g/cm³, ensuring optimal mass-to-volume ratio.
- Melting Range: Optimal range between 1290-1350°C, facilitating versatile applications.
- Structure: Features a face-centered cubic lattice, evolving to stable Ni3(Nb,Ti) phases post heat treatment at around 650°C.
4. Key Features
- Corrosion Resistance: Exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking in harsh chloride, acidic, and marine environments.
- High-Temperature Stability: Retains remarkable strength and oxidation resistance at temperatures up to 1800°F (982°C).
- Versatility: Ideal for welding dissimilar metals (such as carbon steel to nickel alloys) and perfect for surface cladding applications.
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; INCOFLUX 7 flux is recommended for SAW processes.
- Wire Diameters: Available in a convenient range of 0.8-3.2 mm, offered as spooled or straight rods.
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: Compatible with INCONEL 625, INCOLOY 825, 20alloy, 9% Ni steel, and numerous dissimilar combinations (e.g., 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: Proudly certified by ABS, NADCAP, and ISO 18274 for use in critical industries, ensuring top-notch quality and reliability.
8. Handling & Storage
- Moisture Control: Ensure your materials are always kept in impeccably dry conditions to maintain their quality and performance. The copper-coated variants are a brilliant choice for improving conductivity, ensuring superior results every time.
- Pre-Weld Prep: Before you start welding, meticulously clean all surfaces to remove any traces of oil, rust, and moisture. Employ low heat input techniques to safeguard against material embrittlement, ensuring long-lasting, high-quality welds.
9. Packaging & Availability
- Packaging: Choose from our convenient packaging options, whether it's spools ranging from 5 to 15 kg or straight rods, to suit your specific project needs.
- Lead Time: Our efficient processing ensures that your order typically ships within a swift timeframe of 3 to 15 days, depending on the quantity ordered, to keep your operations running smoothly.
Summary: Our High-Performance ERNiCrMo-3 Nickel Alloy Welding Wire stands as the ultimate choice for demanding environments. It boasts unmatched mechanical strength, exceptional corrosion resistance, and versatile adaptability, making it the preferred solution across a variety of industries.
