AWS ERNiCr-3 (N06082) Weld Metal

AWS ERNiCr-3 is a nickel-based filler metal for welding. Cited properties are appropriate for the as-welded condition. ERNiCr-3 is the AWS designation for this material. N06082 is the UNS number. The graph bars on the material properties cards below compare AWS ERNiCr-3 to: nickel-based welding fillers (top), all nickel alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
