• Impurities: Minimal to Maximize Reliability: With iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%) carefully restricted, risks of cracking are significantly minimized, ensuring durability.

2. Mechanical Properties: Built to Endure

• Tensile Strength: Robust and Reliable: ≥760 MPa - engineered for outstanding tensile integrity.
• Yield Strength: Formidable Resilience: ≥420 MPa - designed to withstand demanding conditions.
• Elongation: Flexibility Meets Strength: ≥27% - ensuring structural adaptability.
• Impact Toughness: Unwavering Performance Under Pressure: With high resistance to fatigue and stress corrosion cracking, this wire excels from cryogenic to high-temperature applications, showcasing its versatility.

3. Physical Properties: Fundamental Strengths

• Density: A Solid Foundation: 8.4 g/cm³ - a testament to its substantial build.
• Melting Range: Broad and Reliable: 1290-1350°C - offering dependable thermal resilience.
• Structure: Stability Through Innovation: Featuring a face-centered cubic lattice that transforms into stable Ni3(Nb,Ti) phases post heat treatment at ~650°C, this structure reinforces its exceptional stability.

4. Key Features: Advancing Industry Standards

• Corrosion Resistance: Unmatched Protection: Exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking is built into its design, making it ideal for chloride, acidic, and marine environments.
• High-Temperature Stability: Consistent Performance: Maintains formidable strength and oxidation resistance up to 1800°F (982°C), embodying reliability in high-heat settings.
• Versatility: Fusion at Its Finest: Ideal for welding dissimilar metals, such as carbon steel to nickel alloys, and perfect for surface cladding, showcasing its adaptability.

5. Welding Process Compatibility: Seamless Integration

• Methods: Comprehensive Suitability: Compatible with TIG (GTAW), MIG (GMAW), submerged arc (SAW), and plasma arc welding, offering broad application possibilities.
• Shielding Gas: Optimal Choices: Utilize argon or argon-helium mixtures for TIG/MIG; INCOFLUX 7 flux is recommended for SAW, ensuring quality results.
• Wire Diameters: Fit for Every Need: Available in 0.8-3.2 mm (spooled or straight rods), catering to diverse applications.

6. Applications: Broadening Horizons

• Industries: From Earth to Sky: Aerospace (engine components, exhaust systems), chemical processing (reactors, pipelines), marine (valves, seawater systems), and oil/gas (wellhead equipment) are just a few areas where this product shines.
• Materials Welded: Connecting the Unconnectable: Perfect for INCONEL 625, INCOLOY 825, 20alloy, 9% Ni steel, and other dissimilar combinations, such as nickel alloys to stainless steel, proving its versatility.

7. Standards & Certifications: Assured Excellence

• AWS/ASME: A Seal of Trust: Complies with AWS A5.14, ASME SFA-5.14, and UNS N06625, underscoring its adherence to rigorous standards.
• Certifications: Recognized and Respected: ABS, NADCAP, and ISO 18274 certifications affirm its suitability for critical industries, ensuring confidence and reliability.

8. Handling & Storage: Care for Longevity

• Moisture Control: Ensure optimal performance by storing in dry conditions; the copper-coated variants are particularly desirable as they enhance conductivity.
• Pre-Weld Prep: For best results, meticulously clean surfaces of oil, rust, and moisture. Employ low heat input to prevent any risk of embrittlement.

9. Packaging & Availability

• Packaging: Available in versatile packaging options like spools weighing between 5-15 kg or as straight rods.
• Lead Time: Typically ready to ship within 3-15 days, with timing contingent on the quantity ordered.

Summary: The ERNiCrMo-3 is a premium-grade welding wire designed for critical applications in extreme environments. It boasts superior mechanical properties, excellent corrosion resistance, and exceptional adaptability, meeting the stringent demands of various industries.
