Product Description
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
