Question - What is Duplex Stainless Steel Flanges

Nascent Pipes & Tubes is one of the top brand manufacturer & stockiest of high quality Duplex Stainless Steel Flanges, which are more prone to precipitation of sigma phase, nitrides and carbides than corresponding austenitic steels, causing embrittlement and reduced corrosion resistance. Duplex Stainless Steel Flanges is hyper steel for service in highly corrosive conditions, where very high mechanical strength is required. Duplex Steel Slip On Raise Face Flanges has high corrosion resistance in chloride containing media, including seawater, which makes the grade an ideal for use in deep-water umbilical’s and a range of other oil and gas applications. As medium-alloy steel, Duplex Stainless Steel Flanges Blind Raised Face Flanges has superior corrosion resistance in most media compared to the standard austenitic stainless steel ASTM 316L and twice the mechanical strength. Duplex Stainless Steels Flanges grades are named duplex because these Duplex Stainless Steel Flanges equivalent grades have a two phase microstructure. This two phase microstructure consists of grains both, Ferritic as well as austenitic stainless steel classes. As the name suggests, the duplex structure gives this Duplex Stainless Steel Flanges Socket weld Flange Material a combination of attractive properties.

Corrosion Resistance –

 As usual with all Stainless Steel Flanges grades, corrosion resistance of a metal or alloy depends mostly on the composition of the metal, in this case stainless steel. For resistance against chloride pitting and crevice corrosion, the content of elements such as chromium, molybdenum and nitrogen are considered as most important. By adding these elements, Duplex Stainless Steel Flanges Manufacturer in India increase the range of corrosion resistance in this grade of stainless steel Flanges. Therefore, Duplex Stainless Steel Pipe Flange Supplier recommend using this stainless steel grade in many operations as the range is similar to the range of corrosion resistance for austenitic stainless steel Flanges grades, i.e. from Type 304 or 316 to 6% molybdenum stainless steels.

Stress corrosion cracking resistance:

Another reason why SORF Flange Supplier in Mumbai recommends using components made from this grade of stainless steel is because they display very good stress corrosion cracking (SCC) resistance. This is a property the ASME b16.5 Duplex Forged Flange has been inherited from the Ferritic side of the Stainless Steel Flanges. SCC could be a problem under certain circumstances like humidity & elevated temperature or environments containing certain chemicals such as chlorides, for standard austenitic Stainless Steel flanges grades such as Types 304 and 316. Therefore, Duplex Blind Flange Suppliers often supply them to industries such as oil & gas, petrochemicals as well as marine industries. For example, Duplex Flange Manufacturer note that the flanges made from this grade of stainless steel often outperform many Stainless Steel Flanges grades. Duplex Steel Weld Neck Raised Face Flanges offers excellent and consistent machining properties for increased cutting speeds, reduced tool wear and set-up times. The formation of intermetallic phases in Duplex Steel Plate Raised Flanges such as sigma phase occurs in the temperature range 600 Degree C - 1000 Degree C and decomposition of ferrite occurs in the range 350 Degree C - 500 Degree C (475 Degree C embrittlement).The basic idea of Duplex Steel Long Weld Neck Flanges is to produce a chemical composition that leads to an approximately equal mixture of ferrite and austenite.
