DETAILED INFORMATION

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.

Main characteristics

  • Excellent resistance to pitting and crevice corrosion
  • Excellent resistance to stress corrosion cracking (SCC) in hydrogen sulfide (H2S) and chloride containing environments
  • High resistance to general corrosion in acidic and caustic environments
  • Excellent resistance to erosion-corrosion
  • Excellent corrosion fatigue properties
  • Exceptionally high mechanical strength
  • Exceptionally high fatigue strength
  • Physical properties that offer design advantages
  • Good weldability

Heat Treatment

In addition to providing maximum strength and durability, the tubes are heat treated as standard. In case more heat treatment is required as a result of additional processing, solution annealing at 1040-1140°C (1905-2085°F) is recommended, followed by rapid cooling in air, water, or a protective atmosphere.

Welding

The weldability of the Sandvik SAF 2707 HD is excellent in heat-affected zones, as austenite reformation is well achieved. Sandvik 27.9.5.L filler material is recommended for welded joints in order to ensure excellent corrosion resistance and mechanical properties. It gives the joint good strength, toughness and corrosion resistance. This filler material has a low chromium content and is ideal for TIG welding, with an interpass temperature of no more than 100°C (212°F) and a heat input range of between 0.2 and 1 kJ/mm. Neither prewarming nor postweld heat treatment is required for shielding or root gas, since the shielding and root gases should be composed of Ar with 2% N and welding grade N, respectively, for shielding gases and root gases, respectively.

 

Fabrication

Machining

As the Sandvik SAF 2707 HD is a dual phase alloy, its cutting parameters (speed and feed) should be lower than those that are recommended for austenitic stainless steels, since its wear profile is different from the wear profile seen in austenitic stainless steels.

Applications

For deepwater umbilicals, Sandvik SAF 2707 HD is a high-performance duplex steel developed to withstand pitting and crevices while offering corrosion resistance, mechanical strength, and fatigue properties that are all required by a duplex steel. Because of its high yield strength, corrosion resistance, and fatigue properties, Sandvik SAF 2707 HD duplex steel is a great choice for a wide range of oil and gas applications, as it is a very durable, high-quality steel. There are a lot of products in Sandvik SAF 2707 HD range, among them are products with high reliability and operational safety, which will result in lower operating costs when the products are used as raw seawater injection lines, control lines, or chemical injection lines where hydrogen sulphide resistance is needed.
