Mitigation of ammonia-induced SCC in a cupronickel alloy by additions of MgCl2

The work presented in Part 1 of this article showed that additions of magnesium chloride (MgCl2) to ammonia solutions reduced the tendency of ammonia-induced stress-corrosion cracking (SCC) initiation in a Cu-5%Ni alloy. The present work was undertaken to study the SCC behavior of the test alloy exposed to ammonia in the presence of varying concentrations of MgCl2. The exposure to MgCl2 additions reduced the severity of the ammonia-induced SCC.
