2507 Super Duplex Tubes Properties and Character
2507 Super Duplex Pipe is super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment. The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion.
2507 Super Duplex Steel have enhanced pitting and crevice corrosion resistance when compared with 300-series austenitic stainless steel or conventional duplex alloys. This can be attributed to the enhanced levels of chromium, molybdenum and nitrogen found in these materials. Alloy 2507 is the most common “super” duplex grade.
Usage of Duplex 2507 Pipe S32750 Stainless Steel should be limited to applications below 6000°F (3160°C). Extended elevated temperature exposure can reduce both the toughness and corrosion resistance of alloy 2507.The high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion.the duplex structure provides 2507 with exceptional resistance to chloride stress corrosion cracking.
S32750 Stainless Steel possesses excellent mechanical properties. Often a light gauge of S32750 Stainless Steel can be used to achieve the same design strength of a thicker nickel alloy. The resulting saving in weight can reduce the overall cost of fabrication.
The chemical composition of Super Duplex Tubing based on high contents of chromium, nickel and molybdenum improves intergranular and pitting corrosion resistance. Additions of nitrogen promote structural hardening by interstitial solid solution mechanism, which raises the yield strength and ultimate strength values without impairing toughness. Moreover, the two-phase microstructure guarantees higher resistance to pitting and stress corrosion cracking in comparison with conventional stainless steel. From the introduction of its first-generation, Duplex steel has seen a steady increase in popularity.
Recently, the production of high-strength, corrosion resistant Super Duplex Pipe has been implemented in the marine and chemical industries, architecture and mast riggings, wire lines, lifting and pulley equipment and well service strands. In fact, development of wire processing techniques has enabled the production of steel wires down to 1mm in diameter.

- 2205, the work-horse grade accounting for more than 80% of duplex usage;
- 25 Cr duplex such as Alloy 255 and DP-3;
- Super-Duplex; with 25-26 Cr and increased Mo and N compared with 25 Cr grades, including grades such as 2507, Zeron 100, UR 52N+, and DP-3W

2507 Super Duplex Tube Marking and Packing
ASTM A789 / ASME SA789 covers grades of average wall thickness, or, if specified on the order, minimum wall thickness, of stainless steel tubing for services requiring general corrosion resistance, with particular emphasis on resistance to stress corrosion cracking. These steels are suscep- tible to embrittlement if used for prolonged periods at elevated temperatures.
The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Within the text, the SI units are shown in brackets. The inch-pound units shall apply unless the M designation of this specification is specified in the order.

Ordering Information
Orders for product under this specification should in- clude the following, as required, to describe the desired material adequately:
Quantity (feet, metres, or number of lengths),
Name of product (seamless or welded tubes),
Grade
Size (outside diameter and average wall thickness, unless minimum wall thickness is specified),
Length (specific or random),
Optional requirements (for product analysis, see Section for hydrostatic or nondestructive electric test, see Section 10
Test report required (see the Inspection section of Specification A1016/A1016M
Specification designation, and
Special requirements.
General Requirements
Product furnished under this specification shall conform to the applicable requirements of specification A1016/ A1016M, unless otherwise provided herein.
Manufacture
The tubes shall be made by the seamless or welded process with no filler metal added.
Heat Treatment
All tubes shall be furnished in the heat-treated condition in accordance with the procedures shown in Table 2. For seamless tubes, as an alternate to final heat treatment in a continuous furnace or batch-type furnace, immediately follow- ing hot forming while the temperature of the tubes is not less than the specified minimum solution treatment temperature, tubes may be individually quenched in water or rapidly cooled by other means.
Product Analysis
1. An analysis of either one billet or one length of flat-rolled stock or one tube shall be made from each heat. The chemical composition thus determined shall conform to the requirements specified.
2. A product analysis tolerance (see the annex table on Chemical Requirements (Product Analysis Tolerances) in Specification A480/A480M) shall apply. The product analysis tolerance is not applicable to the carbon content for material with a specified maximum carbon of 0.04 % or less.
3. If the original test for product analysis fails, retests of two additional billets, lengths of flat-rolled stock, or tubes shall be made. Both retests for the elements in question shall meet the requirements of this specification; otherwise, all remaining material in the heat shall be rejected or, at the option of the producer, each billet or tube may be individually tested for acceptance. Billets, lengths of flat-rolled stock, or tubes that do not meet the requirements of this specification shall be re- jected.
NOTE 1—For flange and flaring requirements, the term lot applies to all tubes prior to cutting of the same nominal size and wall thickness that are produced from the same heat of steel. When final heat treatment is in a batch-type furnace, a lot shall include only those tubes of the same size and from the same heat that are heat treated in the same furnace charge. When the final heat treatment is in a continuous furnace, or when heat treated condition is obtained directly by quenching after hot forming, the number of tubes of the same size and from the same heat in a lot shall be determined from the size of the tubes as prescribed in Table 3.
NOTE 2—For tension and hardness test requirements, the term lot applies to all tubes prior to cutting, of the same nominal diameter and wall thickness that are produced from the same heat of steel. When final heat treatment is in a batch-type furnace, a lot shall include only those tubes of the same size and the same heat that are heat treated in the same furnace charge. When the final heat treatment is in a continuous furnace, or when heat treated condition is obtained directly by quenching after hot forming, a lot shall include all tubes of the same size and heat, heat treated in the same furnace at the same temperature, time at heat, and furnace speed, or all tubes of the same size and heat, hot formed and quenched in the same production run.
Mechanical Tests Required
1. Tension Tests—One tension test shall be made on a specimen for lots of not more than 50 tubes. Tension tests shall be made on specimens from two tubes for lots of more than 50 tubes (see Note 2).
2. Flaring Test (for Seamless Tubes)—One test shall be made on specimens from one end of one tube from each lot (see Note 1) of finished tubes. The minimum expansion of the inside diameter shall be 10 %.
3. Flange Test (for Welded Tubes)—One test shall be made on specimens from one end of one tube from each lot (see Note1) of finished tubes.
4. Hardness Test—Brinell hardness tests or Rockwell hardness tests shall be made on specimens from two tubes from each lot (see Note 2).
5. When more than one heat is involved, the tension, flaring, flanging, and hardness test requirements shall apply to each heat.
6. Reverse Flattening Test—For welded tubes, one reverse flattening test shall be made on a specimen from each 1500 ft [450 m] of finished tubing.
Hydrostatic or Nondestructive Electric Test
1 Each tube shall be subjected to the nondestructive electric test or the hydrostatic test. The type of test to be used shall be at the option of the manufacturer, unless otherwise specified in the purchase order.
2. The hydrostatic test shall be in accordance with Speci- fication A1016/A1016M, except that in the calculation of the hydrostatic test pressure 64000(441.2) shall be substituted for 32000(220.6).
