A 0.5 oz/f£t2 zinc coating will protect steel wire rope for about 6 
months in seawater. 
Polyurethane and polyethylene sheaths protect steel wire ropes, 
but improvements must be made in the terminations to prevent seawater 
intrusion. 
AISI Type 304 stainless steel wire rope would not be recommended 
for seawater applications. 
Wire ropes fabricated of alloys Ni-Cr-Mo 103, Ni-Cr-Mo 625, Ni-Mo- 
Cr "C", Ni-Co-Cr-Mo and Co-Cr-Ni-—Fe-Mo would be recommended for trouble- 
free seawater applications where the cost can be justified. 
Fiberglass monofilament wires would not be recommended for seawater 
applications because of their embrittlement.
