The issue of cost effective materials selection for safe and reliable performance is an important one to the marine industry. Numerous laboratory data and field service experience are available to users and designers of marine equipment. This information includes data that covered materials as carbon steel on the low end of marine corrosion resistance, to data on the more resistant copper and copper base alloys, stainless steels, nickel base alloys, and up the ladder to the most resistant material such as titanium and alloys of Ni-Cr-Mo family.

This paper presents corrosion data on a relatively new class of super-austenitic stainless steels generally known as the 6 moly steels. These are increasingly being considered and used as a construction material in the offshore industry for handling seawater and hydrocarbon/seawater mixtures containing hydrogen sulfide.
