What Super Duplex 2507 Flanges?

We are prominent manufacturers, suppliers, exporters, and stockists of Super Duplex 2507 Flanges, and we emphasize the fact that the yield strength of the said alloy is approximately twice that of annealed austenitic stainless steels such as 304 and 316. Super Duplex 2507 flanges are manufactured from a high-performance stainless steel alloy composition, basically containing 25% chromium, 4% molybdenum, and 7% nickel, and due to that factor, they are pretty renowned for their exceptional mechanical strength along with superiority in resisting localized corrosion, particularly in chloride-based environments.

Strength and durability of Super Duplex 2507

Super Duplex 2507 flanges have been characterized by their high impact and mechanical strength, good resistance to pitting and crevice corrosion, and excellent stress corrosion resistance. Their good qualities make them suitable for use in temperature applications as high as 570°F with no significant loss of strength. That is one of the main reasons they are seen being used in most of the really harsh environments.

Resistance to corrosion

One of the high spots of Super Duplex 2507 flanges is outstanding resistance to corrosion in water environments containing chloride. The high contents of molybdenum, chromium, and nitrogen in this alloy secure excellent resistance to chloride-induced pitting and crevice corrosion, while the ferritic-austenitic structure provides particularly good resistance to stress corrosion cracking in warm chloride conditions. These flanges will also provide good resistance to organic acids such as formic and acetic acids and inorganic acids, particularly those containing chlorides. Due to the low carbon content in Super Duplex 2507, carbide-related intergranular corrosion is practically impossible; hence, it only measures 0.020% carbon weight.

Applications and Features

Super Duplex 2507 is one versatile component used to connect pipes, valves, pumps, and other pieces of equipment in piping systems. Such flanges give an easy way to access maintenance or modification easily. Normally, Super Duplex 2507 flanges are screwed or welded up, and three components are there: the pipe flange, bolts, and gasket. A couple of flanges are bolted together with a gasket between them to form a flanged joint that ensures leakage won't occur. They can be heat treated within the temperature range of 1040 to 1120 °C and then rapidly cooled either by air or water quench. A182 super duplex flanges are either welded or threaded for easy adaptation into piping systems where there is a need to have easy disassembly and access to the components of the system

Super Duplex 2507 flanges have good resistance in the oxidized state at high temperatures, but, as with all duplex stainless steels, they are susceptible to embrittlement when exposed for substantial periods to temperatures above 300 °C. Their relatively low hot strength is likely to necessitate support during heat treatment or forging, and hot forging followed by solution treatment should be used to derive optimum properties

The types of super duplex flanges are as follows: We have different types of Super Duplex 2507 flanges, like socket weld flanges, lap joint flanges, slip-on flanges, blind flanges, weld neck flanges, threaded and screwed flanges. Being one of the best manufacturers, suppliers, exporters, and stockists, we cater the best quality and performance of our flanges to various applications.
