2507 Core Product Features & Performance	• Superior chloride resistance: PREN ≥42 Resists pitting, crevice, and stress corrosion cracking in seawater, brine, and chloride-rich industrial media. • High strength and rigidity: Ideal for high-pressure, high-temperature, and heavy-load piping. • Excellent uniform corrosion resistance: Stable in acidic, alkaline, and saline environments. • Good erosion–abrasion resistance: Handles slurries and particle-laden flows. • Long service life: Low maintenance and high durability in harsh conditions.
2507 Applications	S32750 / 2507 super duplex stainless steel pipe is widely applied in extreme corrosive industrial fields: • Offshore oil & gas platforms, subsea pipeline systems • Seawater desalination, seawater cooling and water injection systems • Power plant FGD (Flue Gas Desulfurization) systems • Chemical & petrochemical processing, acid medium transportation • Pulp & paper bleaching production lines • Marine engineering, coastal industrial facilities • Wastewater treatment and salt chemical industry

Super duplex UNS S32750 (2507) is a high-alloy duplex stainless steel with roughly equal austenite and ferrite phases. It delivers high yield strength, exceptional resistance to pitting, crevice corrosion, and stress-corrosion cracking—outperforming conventional austenitic steels. Its composition makes it ideal for aggressive chloride environments, including offshore oil and gas, desalination, and chemical processing.
Super duplex UNS S32750 (2507) Duplex stainless steel Application Super duplex stainless steel S32750 is preferred for seawater applications over standard duplex grades like S32205.And S32507 due to its higher pitting resistance—evidenced by a PRE number >40. Its superior resistance to pitting, crevice corrosion, and stress corrosion cracking makes it widely used in chemical processing, pharmaceuticals, pulp and paper, seawater systems, and flue gas desulfurization.
