This paper presents the findings of a failure analysis performed on brass electrical connectors (pins) that had failed during service in outdoor switch yards, and the results of laboratory studies performed in conjunction with the failure analysis. The results conclusively indicate that the failure of the electrical connectors was the result of intergranular SCC in the outdoor environment. The cracks propagated in the connectors along the interface between a severely cold-worked microstructure and a more …
