Duplex Steel Flanges

Amardeep Steel Centre is actively engaged in manufacturer, supplying & exporting Duplex Steel S31803 & S32205 Flanges in India. We offer the complete range of Flanges including Slip on, socket weld, blind, lapped, screwed, weld neck, reducing etc. ANSI B16.5 Duplex Blind Flange tends to offer significantly better toughness as well as ductility when compared to Ferritic stainless steel grades. These ASME SA182 Duplex Steel Flanges are available in various size, shapes, specification & thickness as per requirements of our clients. These are widely used in various application industry like Chemical Industry, Oil & Gas, Fertilizer, Engineering Industry etc. Another reason why Duplex Stainless Steel S31803 & S32205 Welded Flange is recommend 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. Duplex Steel Flange consists elements such as chromium, molybdenum and nitrogen are considered that offers resistance against chloride pitting and crevice corrosion. 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. As a well-known Manufacturer, Supplier & Stockist, we offer these ASTM A182 Duplex Steel S31803 & S32205 Flanges at very competetive prices for our customer.
