✅ Common grades include 254SMO, AL-6XN, 904L, and Super Duplex 2507, all offering PREN values above 40 for excellent pitting and crevice corrosion resistance.
✅ These steels are alloyed with high levels of molybdenum, nitrogen, and chromium to ensure superior localized corrosion protection.
✅ Used in desalination plants, offshore pipelines, pressure vessels, and pharmaceutical systems where regular stainless steels fail.
