Duplex Steel S31803 and the tubes, known also by the universal standard name ASTM A789 and the numbering UNS number S31803, are greatly valued due to high strength, and superb corrosion resistance. The manufacture of these tubes is done with a ferritic austenitic microstructure which provides twice as much strength that of the austenitic stainless steels. At Hindco Steel And Alloys we specialise in manufacturing and distribution of high quality Duplex Steel S32205 Tubes that satisfies the demand of the international industry and more to the customer.
Hindco Steel And Alloys as a renowned manufacturer and supplier of Duplex Steel S32205 Tubes also maintains the quality at a highest level through incorporation of modern manufacturing sins, stringent quality checks and execution within the international norms. These tubes find extensive application in oil and gas discovery works, in petrochemical processing, chemical, petrochemical and heat exchangers and also in marine as their high durability and resistance to corrosion is vital. The tubes are very strong and can be welded easily and are therefore suitable to fabrication and high-pressure lines.
UNS S32205 of a universal standard name Duplex 2205 fits the strict demand of structural integrity in environments that are chloride-rich and acidic. This improvement also comes with the fact that they contain chromium (22%), molybdenum (3%), and nitrogen that improves passivity and pitting resistance of the tubes and increases their lifespan, particularly when subjected to harsh media. Depending on the ASTM specifications, these tubes can be made both seam and welded at special measurement and thicknesses and finishes to fit different application needs.
We are dealing with an international client base at Hindco Steel And Alloys since we provide a quick delivery, reasonable prices and technical support. This adherence to international standards, customer satisfaction makes us one of the preferred suppliers and makers of Duplex S32205 Tubing in the local and international markets.
