2. Duplex stainless steel - Wikipedia

   en.wikipedia.org/wiki/Duplex_Stainless_Steel

   The main differences in composition, when compared with austenitic stainless steel is that duplex steels have a higher chromium content, 20–28%; higher molybdenum, up to 5%; lower nickel, up to 9% and 0.05–0.50% nitrogen. Both the low nickel content and the high strength (enabling thinner sections to be used) give significant cost benefits.

   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 ...

5. List of steel producers - Wikipedia

   en.wikipedia.org/wiki/List_of_steel_producers

   The World Steel Association features a list from its members every year. Due to mergers, year-to-year figures for some producers are not comparable. Not all steel is the same. Some steel is more valuable than other steel, so the volume is not the same as turnover. Some of the world's leading steel producers include China Baowu Group and ...

6. Stainless steel - Wikipedia

   en.wikipedia.org/wiki/Stainless_steel

   Duplex stainless steels have a mixed microstructure of austenite and ferrite, the ideal ratio being a 50:50 mix, though commercial alloys may have ratios of 40:60. They are characterized by higher chromium (19–32%) and molybdenum (up to 5%) and lower nickel contents than austenitic stainless steels.
