The consequences of crevice corrosion are generally more severe than for pitting corrosion. By definition, a crevice will tend to be relatively deep and narrow in comparison with a pit, which will tend to be shallower or wider. Therefore, the reduction in the effective thickness of a part could be significant, reducing its ability to support the load or meet the pressure rating of the component it was originally designed to handle. In addition, depending upon the depth and shape of the crevice, and its location, it could act as a stress concentrator, greatly increasing the likelihood of it acting as a crack and propagating, resulting in catastrophic failure.
