Filler metal of AWS A5.14 Class ERNiCr-3 (67% Ni--20% Cr--3% Mn--2.5% Nb), often known as Inconel 82, is conventionally used for austenitic-to-ferritic dissimilar-metal transition weld joints. For example, this filler metal is proposed for use in the transition joints for the steam generator system of the Clinch River Breeder Reactor Plant. Recent efforts to develop analytical descriptions of the creep and creep-rupture behavior of ERNiCr-3 weld metal are described. These results are compared with previous analyses of the bahavior of 2 1/4 Cr--1 Mo steel and alloy 800H, the two base metals that would be joined by the ERNiCr-3 filler metal in one of the proposed CRBRP transition joints.
