Alloyed Sustainables LLP Super Duplex Pipes

 

Duplex stainless steels are graded for their corrosion performance, normally determined by their alloy content. Super-Duplex falls under this family of grades. The term was first used in the 1980s and was used to classify Duplex that had a pitting resistance of >40 (based on Cr% + 3.3Mo% + 16N%).

Super Duplex has all the benefits of other duplex steels, specifically the strength benefits of their biphasic structural composition of equal parts austenitic and ferritic stainless steel. This microstructure makes all duplex steels around twice as strong as regular single structure ferritic or austenitic steels, but Super Duplex has a higher chromium and molybdenum content, giving it considerably increased resistance to corrosion than its counterparts.

 

Super Duplex vs Duplex 
 

Super duplex and duplex stainless steels both have the same three metals in common, these metals are present at different levels. Duplex consists of 22% chromium, 5-6% nickel and 3% molybdenum. Super duplex, meanwhile, contains 25% chromium, 7% nickel and 4% molybdenum. The higher levels of these elements is what gives super duplex its enhanced resistance to corrosion against duplex stainless steel.

Super duplex steel, largely due to its higher nickel content, is more expensive than duplex stainless steel. Super duplex, however, can withstand corrosive environments such as those found in marine or petrochemical industries for a longer time than duplex and is higher in strength.

Applications of Super Duplex
 

Super duplex is particularly suited for the following applications:

Heat exchangers, tubes and pipes for processing gas and oil

Pipes in processes containing chlorides

Cargo tanks – piping for chemical tankers

Shafts, rotors and hydraulic lines

The high strength and low corrosion of super duplex means it is widely used in the following industries

Petrochemical

Water desalinisation

Chemical processing

Marine and shipping

Oil and Gas production
