Duplex 2205 2507 2201 Stainless Steel Plate Hot Rolled 3.0 - 80.0mm Waterjet Cutting as Request


Duplex stainless steels are called “duplex” because they have a two-phase microstructure consisting of grains of ferritic and austenitic stainless steel. The picture shows the yellow austenitic phase as “islands” surrounded by the blue ferritic phase. When duplex stainless steel is melted it solidifies from the liquid phase to a completely ferritic structure. As the material cools to room temperature, about half of the ferritic grains transform to austenitic grains (“islands”). The result is a microstructure of roughly 50% austenite and 50% ferrite.

Feather of duplex stainless steel

  • Strength: Duplex stainless steels are about twice as strong as regular austenitic or ferritic stainless steels.
  • Toughness and ductility: Duplex stainless steels have significantly better toughness and ductility than ferritic grades; however, they do not reach the excellent values of austenitic grades.
  • Corrosion resistance: As with all stainless steels, corrosion resistance depends mostly on the composition of the stainless steel. For chloride pitting and crevice corrosion resistance, their chromium, molybdenum and nitrogen content are most important. Duplex stainless steel grades have a range of corrosion resistance, similar to the range for austenitic stainless steels, i.e from Type 304 or 316 (e.g. LDX 2101©) to 6% molybdenum (e.g. SAF 2507©) stainless steels.
  • Stress corrosion cracking resistance: Duplex stainless steels show very good stress corrosion cracking (SCC) resistance, a property they have “inherited” from the ferritic side. SCC can be a problem under certain circumstances (chlorides, humidity, elevated temperature) for standard austenitics such as Types 304 and 316.

About 2205 duplex stainless steel


Duplex 2205 is a two-phase, ferritic, austenitic 22% chromium, 3% molybdenum, 5 to 6% nickel alloyed stainless steel. It is the most widely used duplex stainless steel grade and is characterized by high yield strength, double that of the standard austenitic stainless steel grades. It also demonstrates good fatigue strength, as well as outstanding resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion in severe environments.

Applications:

  • Chemical processing, transport and storage – pressure vessels, tanks, piping, and heat exchangers
  • Oil and gas exploration and processing equipment – piping, tubing, and heat exchangers
  • Marine and other high chloride environments
  • Effluent scrubbing systems
  • Pulp and paper industry – digesters, bleaching equipment, and stock-handling systems
  • Cargo tanks for ships and trucks
  • Food processing equipment
  • Biofuels plants

Standards:

  • ASTM/ASME: A240 UNS S32205/S31803
  • EURONORM: 1.4462 X2CrNiMoN 22.5.3
  • AFNOR: Z3 CrNi 22.05 AZ

About 2507 duplex stainless steel


Alloy 2507 (UNS S32750) is a 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. The high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion.

Applications

  • Oil and gas industry equipment
  • Offshore platforms, heat exchangers, process and service water systems, fire-fighting systems, injection and ballast water systems
  • Chemical process industries, heat exchangers, vessels, and piping
  • Desalination plants, high pressure RO-plant and seawater piping
  • Mechanical and structural components, high strength, corrosion-resistant parts
  • Power industry FGD systems, utility and industrial scrubber systems, absorber towers, ducting, and piping

Mechanical and Physical Properties

2507 combines high tensile and impact strength with a low coefficient of thermal expansion and high thermal conductivity. These properties are suitable for many structural and mechanical components. The low, ambient, and elevated temperature mechanical properties of 2507 sheet and plate are shown below. All of the test data shown are for samples in the annealed and quenched condition.

2507 is not recommended for applications which require long exposures to temperatures in excess of 570°F because of the increased risk of a reduction in toughness. The data listed here are typical for wrought products and should not be regarded as a maximum or minimum value unless specifically stated.
