What are Duplex Steel S31803 Tubes?

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 S31803 Tubes that satisfies the demand of the international industry and more to the customer.
