...Abstract As process conditions in the oil and gas industry become more demanding, the number of potential application areas requiring the use of high-performance superaustenitic stainless steels has increased. This has led to the reintroduction of the UNS S32654 grade (24Cr, 22Ni, 7.3Mo, 3Mn, 0.5N...

...) are presented. crevice corrosion seawater nickel based alloys superaustenitic stainless steel INTRODUCTION Ni-Cr-Mo alloys, such as Alloy 625 (UNS N06625) and highly alloyed stainless steels have been extensively used in marine applications such as offshore platforms, desalinisation plants or military...

...Abstract With the recent interest in superaustenitic stainless steels and nickel-base alloys for materials of construction in pharmaceutical applications, specifications have been created to assure the best possible finish after electropolishing. These specifications require extensive...

... the remaining gap, a new superaustenitic stainless steel has been developed that maintains the attractive cost of the 6% Mo alloys, but enhances both corrosion resistance and strength to open up environments that were too severe for 6% Mo alloys. The development of this alloy along with localized corrosion...
