ERNiCrMo-3 Nickel Alloy Welding Wire
1. Chemical Composition
Introducing the ERNiCrMo-3 (AWS A5.14), a masterfully crafted nickel-chromium-molybdenum alloy. Its precisely controlled elemental composition guarantees unparalleled high performance:
- Primary Elements: Nickel (Ni: 58-62%), Chromium (Cr: 20-23%), Molybdenum (Mo: 8-10%), Niobium (Nb: 3.15-4.15%)
- Impurities: Designed with low levels of iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%) to significantly reduce cracking risks and enhance integrity.
2. Mechanical Properties
- Tensile Strength: A robust tensile strength of ≥760 MPa ensures durability and reliability.
- Yield Strength: Yield strength stands at an impressive ≥420 MPa, promising consistent performance.
- Elongation: Elongation at ≥27% offers excellent flexibility and adaptability.
- Impact Toughness: Exhibits outstanding resistance to fatigue and stress corrosion cracking, perfect for applications ranging from cryogenic temperatures to high-temperature extremes.
3. Physical Properties
- Density: With a density of 8.4 g/cm³, it's both light and durable.
- Melting Range: A melting range between 1290-1350°C ensures high thermal stability.
- Structure: Featuring a face-centered cubic lattice structure, transitioning to stable Ni3(Nb,Ti) phases post heat treatment at ~650°C for enhanced durability.
4. Key Features
- Corrosion Resistance: Provides exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, making it ideal for chloride, acidic, and marine environments.
- High-Temperature Stability: Retains strength and oxidation resistance even at high temperatures up to 1800°F (982°C).
- Versatility: Perfectly suited for welding dissimilar metals such as carbon steel to nickel alloys and for surface cladding purposes.
5. Welding Process Compatibility
- Methods: Compatible with a range of welding methods including TIG (GTAW), MIG (GMAW), submerged arc (SAW), and plasma arc welding for maximum flexibility.
- Shielding Gas: Use argon or argon-helium gas mixtures for TIG/MIG; INCOFLUX 7 flux is recommended for optimal results in SAW.
- Wire Diameters: Available in versatile diameters of 0.8-3.2 mm, offered as spooled or straight rods to suit diverse needs.
6. Applications
- Industries: Widely applied in aerospace (engine components, exhaust systems), chemical processing (reactors, pipelines), marine (valves, seawater systems), and oil/gas sectors (wellhead equipment).
- Materials Welded: Capable of welding materials such as INCONEL 625, INCOLOY 825, 20alloy, 9% Ni steel, and various dissimilar material 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 top-tier quality and reliability.
- Certifications: Proudly certified by ABS, NADCAP, and ISO 18274, making it ideal for critical industries.
8. Handling & Storage
- Moisture Control: Ensure the highest performance by storing in dry conditions; the copper-coated variants are designed to enhance conductivity, providing superior welding results.
- Pre-Weld Prep: Prepare your surfaces meticulously by removing oil, rust, and moisture. Use low heat input to prevent embrittlement and guarantee top-quality welds.
9. Packaging & Availability
- Packaging: Available as versatile spools ranging between 5 and 15 kg, or as straight rods to meet diverse welding needs.
- Lead Time: Efficient logistics ensure that orders typically ship within 3-15 days, dependent on quantity, to keep your projects on schedule.
Summary: ERNiCrMo-3 is an elite welding wire crafted for the most demanding environments, offering a blend of robust mechanical properties and exceptional corrosion resistance. Its adaptability makes it indispensable across a myriad of industries.
