Duplex Plate


What is Duplex Plate?

Alloy 2205 is a microstructure of stainless steel. The ferritic, austenitic grade Duplex plate is designed with a superior chemical concentration of chromium, nickel, and molybdenum coupled with a few other elements. The superior composition of the Duplex 2205 Steel Plate allows these modules to work well in corrosive and oxidative media. The high strength grade of Duplex Steel 2205 Plate shows excellent resistance against pitting by acids and crevice corrosion across different stress-induced environments.

Exhibiting twice the strength of normal grades, the SS Duplex 2205 Plate performs well in applications in temperature ranges between -50 degrees F and as high as 600 degrees F in the system. With a higher heat conductivity, the Duplex 2205 Sheet, exhibits lower thermal expansion. These modules are annealed at a minimum temperature of 1900 degrees F. This Duplex 2205 Stainless Steel Sheet is commonly seen in use in chemical processing equipment, distillation components, oil and gas exploration, high chloride marine environments, and so on.

Buy Duplex plate in Custom Dimension to avoid wastage

It is important to buy Duplex plates of the correct dimension to save money as well as prevent wastage. The Duplex Plate Dimensions vary from project to project selecting, and getting the correct dimensions will help the project be on time and work to progress faster. To get the accurate weight the Duplex Plate Weight Calculator can be employed to measure the modules accordingly. Some plates have to be designed with appropriate composition and processing, like the SA-240 Duplex 2205 Cold Rolled Plate to get the desired results for specific projects.


SAF 2205 plate vs 2507 plate

saf 2205 and 2507 plate are austenitic and ferritic microstructures. Both these components can be differentiated based on certain features.
  • The SAF 2205 plate is designed with a chemical concentration of 23% of chromium, while the content of chromium in the 2507 plate is up to 25%. The higher content gives these modules superior corrosion resistance properties.
  • Duplex grade can be easily machined compared to the marine grade 2507 plate.
  • Duplex plates are cheaper in comparison to super duplex plates.

Duplex Plate Material Grade

Dual microstructure ferritic and austenitic duplex plate is a high-strength steel component. ASTM A240 Type 2205 Sheet material grade is specified with a UNS No of S31803 / S32205, Euronorm- X2CrNiMoN22-5-3. The material of the UNS S32205 Strip has superior mechanical properties with a minimum yield strength of 448Mpa coupled with a tensile strength of a minimum 621mpa.

The DIN 1.4462 Coil can be elongated by a minimum of 25% while exhibiting a superior hardness of 239 max Brinell HB. The density of the Duplex S31803 Foil is 782 kg/m3 with an elastic modulus of 190 GPA


Duplex Stainless Steel Hot Rolling

Duplex stainless steel is recommended to be formed below 600 degrees F. During the hot forming process, the steel should be uniformly heated at temperatures between 1750 to 2250 degrees F. The soft component is easily formed at this temperature. If these modules are worked in temperatures higher than 2205 degrees F the module will tear.

Similarly, if it is processed below the temperature range, the austenitic grade will overpower the ferritic grade leading to cracking. After the procedure, the module should be solution annealed in temperatures of 1900 degrees F followed by rapid quenching to restore the hardness, balance, and corrosion resistance.

Thickness Diffrenece of Duplex 2205 Plate and Sheet?

Plates and sheets form the major components of the Duplex 2205 grade. The Duplex 2205 Plate Thickness starts at above 6mm and can extend to 150mm. These strong modules are added to provide stability and durability to any infrastructure. A sheet-like WERKSTOFF NR. 1.4462 Perforated Sheet is designed in thickness below 6mm.

These modules are added to structures to improve the looks and cut down on weight. Designed with thickness of over 0.020mm, the SAF 2205 Shim Sheet fills spaces in between different components in the metal industry.

To give an aesthetical appeal to the grade, the Alloy 2205 2B Finish Sheet exhibiting a reflective polished finish is utilized.

Why Duplex 2205 Stainless Steel Sheet is appropriate in Marine environments?

The dual microstructure alloy 2205 is designed with a superior chemical concentration of chromium, nickel, and molybdenum. The superior concentration gives these modules enhanced corrosion and oxidation resistance in marine environments. The content of molybdenum within this grade gives these modules resistance to pitting by chlorides, which is common in marine environments. The Duplex 2205 Plate Application are common in marine grade systems as well as in chemical processing systems. These modules are also seen in piping and transportation units.
