A Super Duplex stainless steel is a type of Duplex stainless steel with enhanced corrosion resistance stocked by M/S Hilton Steel. As a part of the Duplex family of stainless steels Super Duplex stainless has a microstructure which is split roughly 50:50 between austenite and ferrite. It differs from Duplex in its chemical composition (with increased amounts of Molybdenum, Nickel, and Chromium) and its mechanical properties (higher proof stress and tensile strength). This highly alloyed product is especially designed for marine, chemical, and oil engineering applications requiring both high mechanical strength and resistance to corrosion in extremely aggressive environments (chloride-containing acids etc.).
Super Duplex stainless steel, relative to other stainless steel products, gives

  • High corrosion resistance
  • High resistance to stress corrosion cracking
  • High yield strength and tensile stre

It is used extensively for offshore oil and gas applications and can be found in flow lines, risers, process vessels, separators, coolers, manifolds, and process piping. Onshore it can be found in heat exchangers, boilers, and pressure vessels in petrochemical and chemical processing plant.

Super Duplex Stainless Steel Sheet & Plate

Hilton Steel holds an extensive stock of Super Duplex stainless steel plate and is one of the few companies to keep both S32750 and S32760 material grades. All stock plate is manufactured by Western European steel makers, third party inspected, and certified.

Plates are stocked which is designed to minimize fabrication costs for our customers by reducing the amount of welding required. The large format also gives us the opportunity to make the best possible use of each plate when "nesting" the shapes required by our customers. Given the specialised nature of this type of steel it is no great surprise that the majority of our sales are made in cut and processed form.

Super Duplex Stainless Steel Round Bar

Hilton Steel is suppliers of UNS S32760 super duplex stainless steel round bar S32760 super duplex grade has enhanced pitting and crevice corrosion resistance in comparison with the ordinary austenitic or duplex types and is suitable for use in aggressive environments. This is due to the higher additions of chromium, molybdenum and nitrogen. This austenitic stainless type grade combines high strength and good ductility with outstanding corrosion resistance qualities. UNS S32760 has excellent resistance to stress corrosion cracking and gives a high resistance to erosion corrosion and corrosion fatigue.
