However, extended exposure to intermediate temperatures (1200\u00b0F – 1600\u00b0F) can cause metallurgical instability. If you want to know how to choose nickel alloy that resists this specific degradation, you must analyze long-term aging data rather than just room-temperature tensile tests.<\/p>\n

A1: The Pitting Resistance Equivalent Number (PREN) calculates an alloy’s resistance to localized pitting based on its Chromium, Molybdenum, and Nitrogen content. In chloride-rich seawater, alloys must typically possess a PREN > 40 (like Alloy 625) to prevent rapid intergranular attack and crevice corrosion under marine biofilms.<\/p>\n
