UNS S32750 & UNS S32760
Super duplex stainless steels are generally more complex, more highly alloyed materials with PREN (Pitting Resistance Equivalent number) = 40.0 and offer even higher strength and corrosion resistance making them suitable for very demanding applications such as offshore marine engineering.
