Duplex Flanges & Super Duplex Steel Flanges

Duplex Steel Flanges, Super Duplex Flanges, Super Duplex Steel S32750 Flanges, Duplex Steel S32760 Flanges, Duplex Steel S31803 Flanges, Duplex Steel S32205 Flanges, ASTM A182 Duplex Flanges Manufacturer in India


Duplex 2205 and Super Duplex 2507 stainless steel flanges are known for their exceptionally high yield strength, which is twice that of annealed yield strength found in typical austenitic stainless steels like 304 and 316. This characteristic makes Duplex 2205 and Super Duplex 2507 steel among the most popular grades for flanges, with Super Duplex 2507 flanges being particularly renowned for their superior corrosion resistance.

The enhanced corrosion resistance of Super Duplex 2507 Flanges makes them well-suited for applications prone to stress-corrosion cracking, crevice corrosion, pitting, erosion, and general corrosion. These properties render Duplex and Super Duplex stainless steel flanges ideal for use in chemical processing, petrochemicals, the power industry, and equipment exposed to seawater. However, it's important to note that the use of Duplex and Super Duplex stainless steel should be limited to temperatures below 570°F, as prolonged exposure to elevated temperatures can lead to embrittlement of the material. The most commonly used grades for duplex flanges are duplex 2205 and super duplex 2507.

Sanghvi Overseas specialises in manufacturing ASTM A182 Duplex UNS S32750/S32760 Flanges that offer superior resistance to pitting corrosion in saline environments, brackish waters, bleaching operations, and certain food processing settings. We supply WNR 1.4410 Super Duplex Steel Weld Neck Flanges paired with stub-ends designed to withstand alkalis at elevated temperatures for offshore marine engineering projects requiring robust yet lightweight components.
