Crevice Corrosion of Stainless Steels and Nickel Alloys under Marine Conditions

Abstract

The susceptibility of stainless steels and high nickel alloys to crevice corrosion severely restricts their use for marine engineering applications. The development of crevice corrosion test procedures for alloy evaluation and development purposes is reviewed. As susceptibility to crevice corrosion is an inherent weakness of this type of alloy, it is suggested that it might in future be more rewarding to determine the design parameters required for the prevention of crevice corrosion by galvanic protection, rather than to pursue the continuing present investment in the quest for the development of an immune alloy.
