The first-generation duplex stainless steels were developed more than 70 years ago in Sweden for use in the sulfite paper industry. Called duplex because of its mixed microstructure with about equal proportions of ferrite and austenite, duplex stainless steels are a family of grades, which range in corrosion performance depending on their alloy content. The term Super Duplex was first used in the 1980s to denote highly alloyed, high-performance "super" duplex steel with a pitting resistance.

BENEFITS OF SUPER DUPLEX STAINLESS STEEL

• High strength,
• High resistance to pitting, crevice corrosion resistance.
• High resistance to stress corrosion cracking, corrosion fatigue and erosion,
• Excellent resistance to chloride stress-corrosion cracking
• High thermal conductivity
• Low coefficient of thermal expansion
• Good sulfide stress corrosion resistance,
• Low thermal expansion and higher heat conductivity than austenitic steels,
• Good workability and weldability,
• High energy absorption.

SUPER DUPLEX APPLICATIONS

• Heat exchangers, tubes and pipes for production and handling of gas and oil,
• Heat exchangers and pipes in desalination plants,
• Mechanical and structural components,
• Power industry FGD systems,
• Pipes in process industries handling solutions containing chlorides,
• Utility and industrial systems, rotors, fans, shafts and press rolls where the high corrosion fatigue strength can be utilized,
• Cargo tanks, vessels, piping and welding consumables for chemical tankers.
• High-strength, highly resistant wiring.

This is a Duplex alloy stainless steel designed to feature high strength, resistance to pitting, stress corrosion cracking, erosion corrosion and corrosion fatigue, crevice corrosion and strong weldability.
Super Duplex Applications

Super Duplex Applications

Oil and gas industry equipment,
Offshore platforms, heat exchangers, process and service water systems, fire-fighting systems, injection and ballast water systems,
Chemical process industries, heat exchangers, vessels, and piping,
Desalination plants, high pressure RO-plants and seawater piping,
Mechanical and structural components, high strength, corrosion-resistant parts,
Power industry FGD systems, utility and industrial scrubber systems, absorber towers, ducting, and piping.

Super Duplex Corrosion Resistance

The high chromium and molybdenum content of Super Duplex makes it extremely resistant to uniform corrosion by organic acids like formic and acetic acid. Super Duplex also provides excellent resistance to inorganic acids, especially those containing chlorides.
