Duplex Steel Pipes & Tubes

Hind Metal Corporation offers a wide range of Duplex Steel S31803 Pipes, which has some excellent features to offer such as high tensile strength, rust-free, wear & tear resistant, etc. Duplex Steel S31803 Seamless Pipes is two-phase, ferritic, austenitic 22 per cent chromium, 3 per cent molybdenum, 5 per cent to 6 per cent nickel alloyed stainless steel. Duplex Steel Welded Pipes is nitrogen enhanced stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless sheets of steel. Duplex Steel S31803 EFW Pipes combines improved resistance to stress corrosion cracking, pitting, crevice corrosion and high strength in comparison with other stainless steel grades. Duplex Steel ERW Pipes is austenitic-ferritic stainless steel, which has superior corrosion resistance and high strength. Meanwhile, these Duplex Steel S31803 Round Pipes are also being offered in different sizes and shapes to our customers. Hind Metal Corporation is one of the pioneer supplier and trader of Duplex Steel S31803 Square Pipes, which is the most widely used duplex (ferritic /austenitic) stainless steel grade. Duplex Steel Rectangular Pipes finds applications due to both excellent corrosion resistance and high strength. Duplex Steel S31803 Electropolish Pipes gives better guaranteed corrosion resistance, but is also resistant to chloride stress corrosion cracking (SCC) at temperatures of up to about 150 Degree C. Duplex Steel Hexagonal Pipes cannot be hardened by thermal treatment, but does work harden.

These S31803 duplex steel pipes and tubes are resistant to corrosion which increases their functional life. They are characterized by high chromium (19 % to 32 %) and molybdenum (up to 5 %) and lower nickel contents than austenitic stainless steels.

The properties of these duplex stainless steels are achieved utilizing having an overall lower alloy content than similar-performing super-austenitic grades, making their use cost-effective for many applications. Meanwhile, we as well offer these pipes and tubes in customized thicknesses and sizes as per the précised requirements given by our valuable customers in the national and international standard quality of raw materials.
