Super Duplex steel S32750 is engineered for extreme performance in highly corrosive environments. Its unique chemical composition with high chromium, molybdenum, and nitrogen content delivers a Pitting Resistance Equivalent Number (PREN) exceeding 40, providing exceptional resistance to localized corrosion. In high-chloride environments like warm seawater, S32750 demonstrates remarkable immunity to stress corrosion cracking (SCC), outperforming standard duplex and most austenitic stainless steels.
