When Marine freight containers were first introduced some 30 years ago they were extensions of then current road transport technology. Involved individuals quickly learned that materials of construction that worked well in a land based environment were far from ideal in a marine, salt laden environment. Corrosion was a major problem. Expert metallurgical advice tempered by real world experience led to the gradual evolution of the current, highly corrosion resistant but not yet perfect aluminum and stainless steel design. Some of the problems that have recently surfaced with aluminum alloys that should have worked and muffler grade stainless steel are explored in this paper. Particular attention is paid to problems in the heat affected zone in the ferritic chromium stainless steels that are used.
