Super Duplex Stainless Steel Tube Suppliers in India

  • Super duplex stainless steel has all of the same benefits as its counterpart the main difference being that this metal has a higher chromium and molybdenum content which provides it with increased corrosion resistance. Super duplex stainless steel is often employed in the oil and gas industry, heat exchangers, offshore platforms, chemical processing equipment, boilers and pressure vessels.

  • Super Duplex Stainless Steel Tube Available Size 1/8″NB TO 30″NB IN

  • Standard of Super Duplex Stainless Steel Tube are ASTM / ASME A/SA 269 / 213 / 249

Super Duplex Stainless Steel Pipe Manufacturers, Suppliers – Top Quality Super Duplex Stainless Steel Pipe Dealers in India!

  • One of the types of duplex stainless steels is the super duplex stainless steel with larger contents of molybdenum, nickel and chromium and mechanical properties of higher yield and tensile strength. As a result super duplex or 2507 grade stainless steel has improved corrosion resistance properties when compared to other duplex stainless steels.
  • Super duplex stainless steel grade 2507 or S32760 exhibits better pitting and crevice corrosion resistance with its PRE being greater than 40 compared to around 35 for Duplex grade 2205, 24 for 316L and 33 for 904L. Super duplex pipes and tubes are widely used in oil refinery heat exchangers, cargo tanks and pressure vessels, seawater applications, desalination plants, refineries and petrochemical plants.
  • Super duplex stainless steel have much in common with authenticate and inferring stainless steels but they have better resistance than most authenticate grades more toughness than most inferring grades and higher strength than most grades of either type. Duplex stainless steels also have the advantage of lower nickel content, making it an attractive option compared to authenticate grades, especially when the cost of nickel is high.

What is a Super Duplex Stainless Steel Tube?

Super duplex is a stainless steel mainly used in oil and gas applications. Super duplex alloys are characterized by a high chromium and molybdenum content. This gives it a high tensile strength which allows it to have better resistance to corrosion cracking and erosion as well as having a high thermal conductivity and a low thermal expansion than conventional authenticate stainless steels. The high chromium and molybdenum content also gives super duplex steel a high resistance to acids that could cause pitting and crevice corrosion.

The unique properties of Super duplex steel mean that it is in high demand for a wide range of scenarios such as pipes in the oil and gas industry, structural and mechanical components, utility and industrial systems, high strength wiring solutions, cargo vessels and heat exchangers. It is well suited for use in many offshore and onshore applications.
