Super Duplex Pipe Steel 

A Super Duplex stainless steel is a type of Duplex stainless steel with enhanced corrosion resistance stocked by Ganyeah Group. 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 Pipe 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.
