Duplex stainless steels (Table 5) have an annealed structure which is typically about equal parts of austenite and ferrite. Although not formally defined, it is gener-ally accepted that the lesser phase will be at least 30% by volume. Duplex stainless steels offer several advantages over the common austenitic stainless steels. The duplex grades are
17-09-2009· "Stainless steel grades suitable for sea water" A discussion started in 2002 but continuing through 2017. 2002. Q. Dear Sir. I am a master student of corrosion engineering in sharif university in Teheran. I have studied in corrosion courses that stainless steel is not resistant to sea water and will corrode (pitting corrosion).
