Duplex 2507 stainless steel is known for its corrosion resistance and exceptional strength. It has about 50-50 ferrite-austenite, though the exact balance may vary with heat treatment. Duplex 2507 stainless steel excels in various demanding industrial applications such as: offshore oil platforms, chemical processing equipment, and marine components.
In this article, we’ll take a closer look at Duplex 2507 stainless steel, including its uses, composition, characteristics, and properties.
Duplex 2507 stainless steel is a super duplex stainless steel containing low carbon (up to 0.03%), chromium (~25%), nickel (~7%), and molybdenum (~4%). Duplex 2507 stainless steel is engineered to meet the rigorous demands of applications that require exceptional strength and resistance to corrosion. These applications include equipment used in chemical processes, petrochemical industries, and equipment used in seawater environments. This steel boasts outstanding resistance to chloride-induced stress corrosion cracking. Thanks to its elevated levels of chromium, molybdenum, and nitrogen, it offers superb protection against pitting, crevice, and general forms of corrosion.
The chemical composition (in weight percentage) and the PREN number of super duplex 2507 stainless steel are given in Table 1 below. Take note that the balance, which is not listed in the table, comprises iron.

Hot forming
2507 should be hot worked between 1875°F and 2250°F. This should be followed by a solution anneal at 1925°F minimum and a rapid air or water quench.
Cold Forming
Most of the common stainless steel forming methods can be used for cold working 2507. The alloy has a higher yield strength and lower ductility than the austenitic steels so fabricators may find that higher forming forces, increased radius of bending, and increased allowance for springback are necessary. Deep drawing, stretch forming, and similar processes are more difficult to perform on 2507 than on an austenitic stainless steel. When forming requires more than 10% cold deformation, a solution anneal and quench are recommended.
Heat Treatment
2507 should be solution annealed and quenched after either hot or cold forming. Solution annealing should be done at a minimum of 1925°F. Annealing should be followed immediately by a rapid air or water quench. To obtain maximum corrosion resistance, heat treated products should be pickled and rinsed.
Welding
2507 possesses good weldability and can be joined to itself or other materials by shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW), plasma arc welding (PAW), flux cored wire (FCW), or submerged arc welding (SAW). 2507/P100 filler metal is suggested when welding 2507 because it will produce the appropriate duplex weld structure.
Preheating of 2507 is not necessary except to prevent condensation on cold metal. The interpass weld temperature should not exceed 300°F or the weld integrity can be adversely affected. The root should be shielded with argon or 90% N2/10% H2 purging gas for maximum corrosion resistance. The latter provides better corrosion resistance.
