Metals Susceptible to Crevice Corrosion

In general, materials that are passive have a greater susceptibility to crevice corrosion. These include aluminum alloys and particularly stainless steels. Titanium alloys normally have good resistance to crevice corrosion. However, they may become susceptible in elevated temperature, acidic environments containing chlorides. In seawater environments, copper alloys can experience crevice corrosion that occurs on the outside of the crevice.
