super Duplex Steel 2507

Super Duplex UNS S32750 Plate is a high-performance duplex stainless steel plate containing approximately 25% chromium, 7% nickel, 4% molybdenum, and nitrogen. Also known as Super Duplex 2507 Plate, it offers exceptional corrosion resistance, high mechanical strength, and excellent resistance to chloride stress corrosion cracking. Manufactured according to ASTM A240 UNS S32750 Plate and ASME SA240 Super Duplex 2507 Plates specifications, it is widely used in offshore, marine, chemical processing, desalination, and oil & gas industries where superior durability is required.

What is Super Duplex UNS S32750 Plate?

Super Duplex UNS S32750 Plate, commonly referred to as Alloy 2507 Plate, is a super duplex stainless steel combining nearly equal amounts of ferrite and austenite. This dual-phase structure provides significantly higher strength than conventional austenitic stainless steels while delivering excellent corrosion resistance.

Manufactured under ASTM A240 UNS S32750 Plate and ASME SA240 Super Duplex 2507 Plates standards, this material performs exceptionally well in chloride-rich and highly corrosive environments. It also offers excellent resistance to pitting, crevice corrosion, stress corrosion cracking, and erosion corrosion.

Equivalent grades include Werkstoff Nr. 1.4410 Plate, while engineers often compare it with the Super Duplex F53 Plate Equivalent because of their similar chemical composition and mechanical properties.
