A: PREN provides a quantifiable metric to predict an alloy’s resistance to localized pitting corrosion, particularly in chloride-rich environments like seawater or chemical processing streams. Specifying an alloy with an appropriate PREN ensures the protective passive oxide layer remains stable, preventing catastrophic tube wall perforation in stagnant zones.<\/p>\n
