What are the applications for super duplex stainless steels?

The term super duplex is typically applied to duplex stainless steels with a chromium content of 25% and a PREN value >40. Pitting Resistance Equivalent Number (PREN) is a quick reference to the corrosion resistance of stainless steels and other corrosion resistant alloys (CRA), which are most likely to be impacted by pitting and crevice corrosion.
