Nickel-containing alloys are identified as candidate materials for fasteners used in seawater or sea atmospheres. The alloys are super high-strength Cu-Ni, stainless steel, and nickel-base alloys. The marine corrosion of the alloys is briefly reviewed. Galvanic and crevice corrosion are critical conditions to consider when selecting fastener alloys. Guidelines are presented to assist designers in the selection of the nickel-containing alloys for marine fastener applications.
