Duplex 2707 (UNS S32707)

A duplex stainless steel alloy that contains Chromium, Nitrogen, Nickel, Molybdenum, and trace amounts of tungsten is known as Duplex 2707 (UNS S33207). This alloy contains these elements, which lead to the formation of intermetallic phases which decrease the impact resistance of SS.

Developed specifically for chemical, oil & gas, deep water umbilical and deep water umbilical applications, duplex grades meet the increasing demands of the chemical industry. Due to its corrosion resistance, such as pitting and crevice corrosion), and its high mechanical strength and tensile strength. In addition to its resistance to stress cracking caused by chlorine and sulfur, the 2707 Duplex (UNS S32707) also resists erosion corrosion, general corrosion in acidic and alkaline environments, as well as excellent weldability. Therefore, they are used in industries such as control lines, raw seawater injections, and chemical injections.

In order to reduce the gauging of the final product (lighter installations are the result), the Duplex Stainless Steel's increased tensile strength could be used, thus proving to be an economically viable option without losing any of its corrosion resistance and strength. The Duplex Stainless Steel Grade 2707 provides greater corrosion resistance, yield strength, and fatigue performance than other super duplex stainless steels. As a result, they find applications in the oil and gas industry.

A duplex is a type of dual phase stainless steel at EN 1.4658 grade, which offers a pitting resistance number (PRE) greater than 48. Examples from this class include SAF 2707 HD (UNS S32707) and SAF 2707 HD (UNS S33207).

Sheets and plates available in 2307 Duplex Products Sheets and Plates are available in standard, non-standard and custom construction options with widths, lengths and thicknesses per your specifications.

A wide range of 2707  Duplex Round Bars is made available by us in various sizes and designs according to customer requirements.

A high quality of 2707 UNS S32707 Pipe, Tubes, Sheet, Plate and Round Bars is available to our client that conforms to the latest market needs. The finish of duplex stainless steel products depends on how much chromium it contains in its raw material. We offer Duplex Stainless Steel Products that are at par with international standards.
