Fitwel Industries LLP is a renowned manufacturers, and suppliers of Super Duplex Steel Flanges Manufacturers in India and abroad, which has an extremely high resistance to various types of corrosion. This is a Super duplex alloy stainless steel designed to feature high strength, stress corrosion cracking, erosion corrosion and corrosion fatigue, and strong weldability. We as well offer these products in custom-built sizes and shapes to our customers. Super Duplex Steel 2507 Flanges is designed to use in demanding applications which require exceptional strength and corrosion resistance such as chemical process, petrochemical and offshore platforms and seawater equipment.
It possesses very high mechanical properties. Super Duplex Steel Flanges (UNS S32760) has excellent resistance to pitting and crevice corrosion resistance compared with the ordinary austenitic or duplex types. Duplex stainless steels grades are named duplex because these Duplex 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 Socket weld Flange Material a combination of attractive properties.
Toughness and ductility: ANSI B16.5 Duplex Blind Flange tends to offer significantly better toughness as well as ductility when compared to Ferritic stainless steel grades. Although Duplex Steel Flanges Suppliers in India appreciate its toughness and ductility, flanges from this grade do not reach or match the excellent values that have been offered by the austenitic stainless steel grades.
Corrosion Resistance: As usual with all stainless steel grades, the 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 increases the range of corrosion resistance in this grade of stainless steel. Therefore, Duplex Stainless Steel Pipe Flange Manufacturers recommends using this stainless steel grade in many operations as the range is similar to the range of corrosion resistance for austenitic stainless steel grades, i.e. from Type 304 or 316 to 6% molybdenum stainless steels.
Stress corrosion cracking resistance: Another reason why Duplex Steel SORF Flanges Supplier in Mumbai recommends using components made from this grade of stainless steel is that 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. 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 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 Manufacturers note that the flanges made from this grade of stainless steel often outperform many stainless steel grades.
Cost: Due to a lower nickel and molybdenum content in Duplex stainless steels, as compared to their austenitic counterparts, they tend to offer similar resistance to corrosion. This is why ASME SA182 Duplex Steel Socket weld Flanges exporter in India quote a lower cost. Lower alloying content, of duplex stainless steels, would mean that the cost can be lowered. This stands true, especially in times of high alloy surcharges. Further, it may often be possible to reduce the section thickness of duplex stainless steel, on account of its increased yield strength when compared to austenitic stainless steel. This combination can lead to significant cost and weight savings in the class 150 duplex pipe flange dimensions when compared to components in austenitic stainless steel grades.
Super Duplex Stainless Steel UNS S32750 Slip On Flanges is a super duplex stainless steel with a 50 / 50 austenite, ferrite microstructure. High impact strength at sub-zero temperatures, Super Duplex Stainless Steel UNS S32760 Blind Raised Flanges displays excellent corrosion resistance. Super Duplex UNS S32750 Spectacle Blind Flanges has enhanced pitting and crevice corrosion resistance in comparison with the ordinary austenitic or duplex types. Super Duplex UNS S32760 Lap Joint Flanges is a super duplex stainless steel supplied in the hot worked and solution annealed condition. The mechanical strength, corrosion resistance, and low-temperature toughness of the Super Duplex S32750 Ring Type Joint Flanges are higher than that of ordinary duplex stainless steels. Super Duplex S32750 Orifice Flanges is the most common super duplex grade that has enhanced pitting and crevice corrosion resistance compared with the ordinary austenitic or duplex types. Super Duplex 2507 Socket Weld Flanges are used for Condensers, Heat exchangers, Dished ends, Filters, and more. Alloy 2507 Weld Neck Flanges is a super duplex stainless steel with a pitting resistance equivalent (PRE) number of more than 40 and provides excellent corrosion resistance and strength properties. Super Duplex DIN 1.4410 Flanges has a higher molybdenum and chromium content which gives the material greater corrosion resistance than standard duplex grades.
