When it comes to composition and mechanical properties, the AWS Class ERNiFeCr-2 filler metal is primarily made up of nickel (about 65-75%), iron (roughly 15-25%), and chromium (8-12%), along with trace amounts of molybdenum and manganese. This unique blend offers excellent resistance to oxidation, stress corrosion cracking, and high-temperature conditions. The weld metal typically boasts a tensile strength of around 80,000–90,000 psi (550–620 MPa), along with good ductility and toughness. ERNiFeCr-2 welds are known for their impressive corrosion resistance and mechanical stability, making them ideal for joining nickel alloys to stainless steels with minimal risk of cracking or distortion.
