   en.wikipedia.org/wiki/Duplex_Stainless_Steel

   Super-duplex (PREN range: 38–45) Typically grade EN 1.4410 up to so-called hyper duplex grades (PREN: >45) developed later to meet specific demands of the oil and gas as well as those of the chemical industries.

3. Zeron 100 - Wikipedia

   en.wikipedia.org/wiki/Zeron_100

   Zeron 100 Super Duplex was born from a research project undertaken by Dr Cecil Roscoe at the University of Manchester, England. Tasked by his then employer – Mather+Platt – with studying the effect of various alloying additions on the mechanical properties and corrosion resistance of Zeron 25, he concluded that an optimum corrosion performance could be obtained from a duplex stainless ...

4. Stainless steel - Wikipedia

   en.wikipedia.org/wiki/Stainless_steel

   Duplex grades are usually divided into three sub-groups based on their corrosion resistance: lean duplex, standard duplex, and super duplex. The properties of duplex stainless steels are achieved with an overall lower alloy content than similar-performing super-austenitic grades, making their use cost-effective for many applications.
