Product Description
ERNiCrMo-3 is a versatile nickel-chromium-molybdenum solid welding wire compliant with AWS A5.14/A5.14M standards, primarily designed for welding INCONEL® 625 (UNS N06625) and similar nickel-based alloys.It features a robust composition with a minimum of 58.0wt.% nickel, 20.0-23.0wt.% chromium, 8.0-10.0wt.% molybdenum, and 3.15-4.15wt.% niobium plus tantalum.This filler metal is compatible with GTAW (TIG), GMAW (MIG), SAW, and PAW processes, making it suitable for joining homogeneous alloys, dissimilar welding between stainless steels and nickel-based alloys, and for corrosion-resistant overlay cladding on steels.Its high alloy content ensures exceptional performance across a wide temperature range, from cryogenic to 1000°F (540°C).
Features
▪ Exceptional Corrosion and Oxidation Resistance: ERNiCrMo-3 provides outstanding resistance to a broad spectrum of corrosive media, particularly excelling in resisting pitting, crevice corrosion, and chloride-induced stress corrosion cracking (SCC).It also demonstrates excellent oxidation resistance at elevated temperatures, ensuring the longevity of welded structures in aggressive environments.
▪ High Strength and Ductility: The weld metal exhibits high tensile strength, typically reaching 115,000 psi (790 MPa), combined with excellent ductility (45% elongation).This combination of properties allows the filler metal to match or exceed the mechanical performance of the base materials while maintaining structural integrity under stress.
▪ Broad Temperature Versatility: ERNiCrMo-3 is engineered for reliable service in environments ranging from cryogenic temperatures to moderately high temperatures up to 1000°F (540°C).Its stable microstructure prevents embrittlement and maintains toughness across this extensive range.
Applications
▪ ERNiCrMo-3 is widely utilized in critical sectors requiring high reliability and corrosion resistance:
▪ Marine & Offshore Engineering: Used for seawater cooling systems, offshore platform components, and submarine hardware exposed to marine environments.
▪ Chemical Processing: Ideal for reactors, heat exchangers, and piping systems handling both oxidizing and reducing acids.
▪ Energy Sector: Applied in power generation flue gas desulfurization (FGD) systems and nuclear reactor components.
▪ Aerospace Industry: Utilized in engine exhaust systems, fuel lines, and hydraulic tubing where high-temperature strength is required.
