Super duplex stainless steel is a type of stainless steel belonging to a special family of steels called the duplex steel. Duplex is a material that is made out of a chromium, molybdenum and nickel alloy. This alloy has a dual nature that contains properties of the ferritic steel and the austenitic steel. This dual nature causes the steel to be stronger and at the same time be corrosion resistant. There are three major groups of duplex; namely, the standard duplex, the super duplex and the lean duplex. The Super duplex has the highest pitting corrosion resistance. The Super duplex stainless steel grades differ ranging from EN1.4410 to some hyper duplex grades that have PREN numbers above 45. The PREN number indicates the composition percentages and the pitting corrosion resistance. The Super duplex steel price varies from supplier to supplier. We offer a competitive price list for our duplex steel products. There are different super duplex applications that use different grades of the material. The addition of nitrogen in the super duplex grades makes the corrosion resistance even higher. Applications in the oil and gas industry, the chemical industry, the marine and sea water industry all use super duplex extensively. To form the necessary intermetallic phases, sometimes tungsten is also used. The higher quantities of these elements make the material harder for processing because of the reduced impact resistance. If handled improperly, the material may crack under stress. Regardless, the Super duplex material properties make the super duplex specifically applicable in different applications. The piping systems in desalination plants, fuel systems, chemical industries and food processing industries use the super duplex grades. There are sheets, plates, pipes, fittings and other accessories made out of this material. The Super duplex steel suppliers sell all the different products of super duplex according to the needs of the customers.
