Product Description

ERNiCrMo-3 Nickel Alloy Welding Wire
1. Chemical Composition
ERNiCrMo-3 (AWS A5.14) is a sophisticated nickel-chromium-molybdenum alloy, engineered with precision to deliver exceptional performance even in the most demanding conditions:

• Primary Elements: Nickel (Ni: 58-62%), Chromium (Cr: 20-23%), Molybdenum (Mo: 8-10%), Niobium (Nb: 3.15-4.15%)
• Impurities: With minimal iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%), this alloy minimizes the risk of cracking, ensuring reliability.

2. Mechanical Properties

• Tensile Strength: ≥760 MPa. Robust and resilient, designed to withstand significant stress.
• Yield Strength: ≥420 MPa. Offers a high threshold for deformation, enhancing structural integrity.
• Elongation: ≥27%. Provides ample flexibility, making it adaptable for various applications.
• Impact Toughness: Remarkable resistance to fatigue and stress corrosion cracking, suitable across a range of temperatures from cryogenic to high heat.

3. Physical Properties

• Density: 8.4 g/cm³. Balances mass and strength for optimal performance.
• Melting Range: 1290-1350°C. Facilitates a broad range of thermal applications.
• Structure: Exhibits a face-centered cubic lattice, evolving to robust Ni3(Nb,Ti) phases after heat treatment around 650°C for enhanced stability.

4. Key Features

• Corrosion Resistance: Superior resistance to pitting, crevice, and stress corrosion in challenging environments such as chloride-rich, acidic, and marine settings.
• High-Temperature Stability: Exceptional strength and oxidation resistance, reliably maintained up to 1800°F (982°C).
• Versatility: Ideal for welding dissimilar metals, like carbon steel to nickel alloys, and for effective surface cladding.

5. Welding Process Compatibility

• Methods: Perfectly 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 advisable for SAW to ensure optimal results.
• Wire Diameters: Available in sizes ranging from 0.8-3.2 mm, either spooled or as straight rods, catering to diverse welding needs.

6. Applications

• Industries: Widely utilized in aerospace (engine components, exhaust systems), chemical processing (reactors, pipelines), marine (valves, seawater systems), and oil/gas (wellhead equipment) sectors.
• Materials Welded: Compatible with materials such as INCONEL 625, INCOLOY 825, 20alloy, 9% Ni steel, and facilitates welding of dissimilar combinations like nickel alloys to stainless steel.

7. Standards & Certifications

• AWS/ASME: Rigorously compliant with AWS A5.14, ASME SFA-5.14, and UNS N06625 standards.
• Certifications: Endorsed by ABS, NADCAP, and ISO 18274 for critical industries, ensuring top-tier quality.

8. Handling & Storage

• Moisture Control: Ensure optimal storage conditions by keeping products in a dry environment. Our copper-coated variants are specifically designed to enhance electrical conductivity, providing superior performance in demanding applications.
• Pre-Weld Prep: For best results, thoroughly clean all surfaces of oil, rust, and moisture before welding. Employ low heat input techniques to prevent embrittlement and maintain the integrity of your welds.

9. Packaging & Availability

• Packaging: Available in versatile packaging options including spools ranging from 5 to 15 kg, as well as straight rods for customized use.
• Lead Time: Our products typically ship within an efficient timeframe of 3 to 15 days, depending on the quantity ordered, ensuring timely delivery for your projects.

Summary: ERNiCrMo-3 is an exceptional welding wire engineered for the most challenging environments. It offers an unbeatable combination of superior mechanical strength, excellent corrosion resistance, and versatile adaptability, making it an indispensable choice across various industries.
