A wide range of tests were used to compare the corrosion resistance of type 434 stainless steel clad aluminum and type 301 stainless steel clad aluminum. The materials were evaluated after each test so that the relative importance of environmental and material factors could be distinguished. Overall results confirm the corrosion resistance achieved by cladding stainless steel with aluminum and indicate that chrome flashing can have a stronger influence than stainless steel composition in automotive trim applications.
