In general, corrosion in surface seawater was more severe than in 

 the deep seawater and in the bottom sediments at depths of 2,500 and 

 6,000 feet for equivalent periods, of exposure. 



Sensitization decreased the corrosion resistance Of AISI Types 304 

 and 316 stainless steels. 



Stainless steel wire ropes were also attacked by the pitting ?.nd 

 crevice types of corrosion. 



Precipitation hardening stainless steels 630-H925, 631-TH1050 and 

 RH1050, 632-RH1100, 15-7AMV-annealed , RH950 and RH1150 and PH14-8Mo- 

 SRH950 failed by stress corrosion cracking.
