Super Duplex Steel Plates, Sheets, and Coils are high-alloy stainless steel flat products designed for extreme corrosion resistance and very high mechanical strength. These products exhibit exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-rich and harsh environments.
Super Duplex Steel Plates / Sheets / Coils are widely used in offshore structures, pressure vessels, chemical processing equipment, desalination plants, and marine applications where superior strength and long service life are critical.
Super Duplex Steel Plates, Sheets, and Coils are available in premium super duplex grades to meet severe service conditions. The most commonly supplied grades include Super Duplex S32750 (UNS S32750) and Super Duplex S32760 (UNS S32760), offering high PREN values, outstanding strength, and excellent resistance to seawater and aggressive chemicals.
