A total of 525 specimens of 60 different alloys were exposed at a depth of 5,900 feet in the Pacific Ocean for 189 days in order to determine the effects of the deep ocean environments on their corrosion resistance. Corrosion rates, types of corrosion, pit depths, and stress corrosion cracking resistance are presented. The materials evaluated were aluminum alloys 5086-H34, H32 and H112 and 6061-T6, and welded and unwelded 5083-H113 and 7039-T64 welded nickel alloys Ni-Cu 400 and K-500, Ni-Cr-Fe 600 and 718, Ni-Cr-Mo 625, and Ni-Fe-Cr 825 and wire ropes Ni-Cr-Mo 625, Ni-Co-Cr-Mo, Ni-Mo-Cr C and Ni-Cr-Mo-103 three high strength-low alloy steels six high strength steels two austenitic cast irons three stainless steels two precipitation hardening stainless steels and stainless steel and modified stainless steel wire ropes and seven welded titanium alloys.
