ERNiCr-4 Welding Wire (Inconel 600 / UNS N06600)
Nickel-chromium alloy filler metal for corrosion and oxidation resistance in high-temperature applications.
Product Overview
ERNiCr-4 is a solid nickel-chromium alloy welding wire specifically designed for welding base metals of similar composition such as Inconel® 600 (UNS N06600). Known for its excellent resistance to oxidation, corrosion, and carburization, this filler metal is ideal for use in high-temperature and chemically aggressive environments.
It is suitable for both TIG (GTAW) and MIG (GMAW) welding processes, offering stable arc characteristics, smooth bead formation, and good mechanical performance. ERNiCr-4 is widely used in the chemical processing, nuclear, aerospace, and marine industries.
Key Features
- Excellent resistance to oxidation and corrosion in high-temperature environments
- Outstanding resistance to carburization and chloride-ion stress corrosion cracking
- Good mechanical strength and metallurgical stability up to 1093°C (2000°F)
- Suitable for welding Inconel 600 and related nickel-chromium alloys
- Easy to weld with stable arc and low spatter in TIG/MIG processes
- Used for overlaying, joining, and repair applications
- Meets AWS A5.14 ERNiCr-4 and equivalent standards
