ERNiCrFe-5 (SNi6062) is a Ni-Cr-Fe-Nb nickel-based solid wire with superior oxidation & chloride stress corrosion resistance and low hot cracking tendency. For Inconel 690/600/601 welding and dissimilar joints, ideal for nuclear and chemical high-temperature corrosive applications.
Welding Characteristics
Applicable Processes: TIG (GTAW), MIG (GMAW)
Polarity: DCEN (DC-)
Low heat input and narrow multi-pass welds recommended; strictly control interpass temperature. Short arc operation preferred for nickel alloys.
Shielding Gas
TIG: 100% high-purity Argon
MIG: 100% Argon preferred; Ar with minor Helium optional for deeper penetration
Back shielding is recommended for root passes to avoid oxidation.
Typical Mechanical Properties (As-Welded)
Tensile Strength: ≥550MPa
Elongation: ≥30%
Good toughness at room and high temperatures.
Key Features
· High-Ni Cr-Fe-Nb alloy resists stress corrosion cracking.
· Excellent high-temperature oxidation resistance and stable mechanical properties.
· Niobium minimizes intergranular corrosion; welds have good ductility and hot crack resistance.
· Stable arc, moderate weld pool fluidity for TIG/MIG welding.
Base Materials
Inconel 690, 600, 601, Incoloy 800; Dissimilar joints of nickel alloys to stainless steel and carbon steel.
Typical Applications
Nuclear power equipment, chemical reactors, furnace components, flue gas treatment facilities and pressure vessels under high-temperature corrosion.
