Product Description ERNiCrMo-3 Nickel Alloy Welding Wire1. Chemical CompositionERNiCrMo-3 (AWS A5.14) is a meticulously engineered nickel-chromium-molybdenum alloy, boasting impeccable elemental precision to deliver unrivaled high performance:Primary Elements: Nickel (Ni: 58-62%), Chromium (Cr: 20-23%), Molybdenum (Mo: 8-10%), Niobium (Nb: 3.15-4.15%) Impurities: Featuring ultra-low iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%), this composition is designed to significantly minimize cracking risks. 2. Mechanical PropertiesTensile Strength: Impressively ≥760 MPa, ensuring robust performance under stress.Yield Strength: ≥420 MPa, providing formidable resistance before deformation.Elongation: ≥27%, offering considerable flexibility and adaptability in various applications.Impact Toughness: Exhibiting high resistance to fatigue and stress corrosion cracking, this wire is ideal for applications ranging from cryogenic to high temperatures.3. Physical PropertiesDensity: 8.4 g/cm3, providing a solid foundation for structural applications.Melting Range: 1290-1350°C, suitable for a wide array of thermal environments.Structure: Featuring a face-centered cubic lattice, with transformation to stable Ni3(Nb,Ti) phases after precise heat treatment around ~650°C.4. Key FeaturesCorrosion Resistance: Offers exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, even in challenging chloride, acidic, and marine environments.High-Temperature Stability: Withstands and maintains both strength and oxidation resistance at 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.5. Welding Process CompatibilityMethods: Compatible across several techniques: TIG (GTAW), MIG (GMAW), submerged arc (SAW), and plasma arc welding. Shielding Gas: Utilizes argon or argon-helium mixtures for TIG/MIG processes; INCOFLUX 7 flux is recommended for SAW.Wire Diameters: Available in diameters ranging from 0.8-3.2 mm, in both spooled or straight rod forms.6. ApplicationsIndustries: Widely used 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 like INCONEL 625, INCOLOY 825, 20alloy, 9% Ni steel, and various dissimilar combinations such as nickel alloys to stainless steel.7. Standards & CertificationsAWS/ASME: This product adheres to AWS A5.14, ASME SFA-5.14, and UNS N06625 standards, ensuring superior quality and reliability.Certifications: Certified by ABS, NADCAP, and ISO 18274, meeting the stringent requirements of critical industries.8. Handling & StorageMoisture Control: Ensure your materials are preserved in optimal conditions by storing them in a dry environment. The copper-coated variants not only enhance conductivity but also provide added protection against moisture infiltration.Pre-Weld Prep: Begin with a thorough cleaning of all surfaces to eliminate any traces of oil, rust, and moisture, ensuring a pristine base for welding. Employ low heat input techniques to prevent metal embrittlement and maintain the integrity of your welds.9. Packaging & AvailabilityPackaging: Available in flexible packaging options such as spools ranging from 5 to 15 kilograms or straight rods, ensuring convenience and suitability for various industrial applications.Lead Time: Expect swift delivery with shipments typically dispatched within 3 to 15 days, contingent on order quantity, ensuring your projects proceed without delay.Summary: The ERNiCrMo-3 is a top-tier welding wire specifically engineered for the most demanding environments. It effortlessly combines superior mechanical strength, outstanding corrosion resistance, and remarkable versatility, making it an ideal choice across a spectrum of industries.Product Description AWS A5.4ERNi-1ERNiCu-7ERNiCr-3ERNiCrFe-5ERNiCrMo-3ERNiCrMo-4ERNiCrMo-7TS(N/mm2)460541671560790729780EL(%)30393930433335C0.020.020.030.030.00370.0020.05Mn0.31.73.0510.030.120.6Si0.160.440.370.040.0290.070.02P0.00120.007/0.0040.0030.0030.003Ti2.3/0.01/0.088//S0.0050.008/0.0020.0010.0015 Cr//19.8615.721.9515.916.7Ni96.565.6872.875.0664.65REMREMCu/REM0.060.030.0090.008/Mo///0.039.0415.915.8Nb//2.42.33.61//V/////0.01/Fe/0.70.237.90.194.122.2
