- Impurities: Features remarkably low levels of iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%) to effectively mitigate the risk of cracking.
2. Mechanical Properties
- Tensile Strength: A robust tensile strength of ≥760 MPa ensures reliability under intense conditions.
- Yield Strength: Capable of withstanding ≥420 MPa of yield strength, manifesting its durability.
- Elongation: Boasting an elongation rate of ≥27%, this alloy offers remarkable flexibility.
- Impact Toughness: Demonstrates outstanding resistance to fatigue and stress corrosion cracking, making it ideal for applications from cryogenic environments to high temperatures.
3. Physical Properties
- Density: With a density of 8.4 g/cm³, it maintains its integrity under demanding conditions.
- Melting Range: A melting range of 1290-1350°C guarantees adaptability in various thermal environments.
- Structure: Featuring a face-centered cubic lattice, transforming to stable Ni3(Nb,Ti) phases upon heat treatment at ~650°C, it ensures structural stability.
4. Key Features
- Corrosion Resistance: Delivers unrivaled resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-rich, acidic, and marine settings.
- High-Temperature Stability: Retains strength and oxidation resistance impressively up to 1800°F (982°C), catering to high-temperature applications with ease.
- Versatility: Perfectly suited for welding a variety of dissimilar metals, such as carbon steel to nickel alloys, and excellent for surface cladding.
5. Welding Process Compatibility
- Methods: Seamlessly integrates with TIG (GTAW), MIG (GMAW), submerged arc (SAW), and plasma arc welding techniques.
- Shielding Gas: Employ argon or argon-helium mixtures for TIG/MIG; INCOFLUX 7 flux is highly recommended for SAW to ensure optimal performance.
- Wire Diameters: Available in a versatile range of 0.8-3.2 mm, offered as spooled or straight rods for diverse applications.
6. Applications
- Industries: Extensively used across aerospace (engine components, exhaust systems), chemical processing (reactors, pipelines), marine (valves, seawater systems), and oil/gas industries (wellhead equipment).
- Materials Welded: Expertly welds materials like INCONEL 625, INCOLOY 825, 20alloy, 9% Ni steel, and also facilitates welding of dissimilar combinations including nickel alloys to stainless steel.
7. Standards & Certifications
- AWS/ASME: Meets rigorous standards with AWS A5.14, ASME SFA-5.14, and UNS N06625 compliance.
- Certifications: Holds prestigious certifications such as ABS, NADCAP, and ISO 18274, serving critical industries with confidence.
8. Handling & Storage
- Moisture Control: Ensure optimal performance by storing the ERNiCrMo-3 Nickel Alloy Wire in dry, controlled environments. Utilizing copper-coated variants enhances conductivity for superior results.
- Pre-Weld Prep: Achieve the best welding outcomes by meticulously cleaning surfaces of any oil, rust, and moisture. Employ low heat input techniques to prevent any potential embrittlement, ensuring a smooth welding process.
9. Packaging & Availability
- Packaging: Available in versatile packaging options, including spools ranging from 5 to 15 kg or as straight rods, designed for your convenience.
- Lead Time: Swift and efficient delivery services ensure your order is typically dispatched within 3 to 15 days, contingent upon the quantity required.
Summary: ERNiCrMo-3 Nickel Alloy Wire is your go-to solution for demanding welding challenges. This premium-grade wire boasts unrivaled mechanical properties, outstanding corrosion resistance, and remarkable adaptability, making it an ideal choice across various industries.
