Super austenitic stainless steel corrosion resistance is higher than the duplex grades, because its alloy content is higher.
Normally super austenitic stainless valves well suited for high chloride environments such as sea water, pulp mill bleach plants, and other high chloride processes.
It has a high PREN (pitting resistance equivalency number) for superior resistance to chloride pitting and stress corrosion cracking.
