Duplex Plate and Sheet

Duplex plate

What is Duplex Plate?

Duplex Plate are a microstructure of ferritic and austenitic grade compounds. These plates are designed to have superior resistance against corrosion and oxidation, allowing them to be utilized across different environments. The plates possess outstanding toughness and exhibit superior ductility. The components exhibit superb strength and crack resistance compared to normal austenitic grades. Duplex plates are designed in sizes above 6mm and can be welded easily. These components are a preferred choice in applications requiring high strengths and durability due to harsh or stress-induced conditions.

What is Duplex Sheet?

Duplex Sheet are metal components that are employed in building different structures that require low levels of durability. Designed with sizes less than 6mm, these sheets are aimed at reducing the weight of the application. The dual microstructure contained within these modules allows them to exhibit outstanding strength and properties, making them stronger than most austenitic grades. They are designed with superior resistance against stress corrosion cracking. The sheets in this range can be corrugated or diamonded to create ridges in the modules. The ridges don’t add extra weight to the component but; help in giving it added strengths.

Duplex 2205 Sheet Characteristics

Some of the characteristics of the Duplex 2205 Sheet include:

  • Dual ferritic and austenitic microstructure
  • Designed in sizes below 6mm
  • Superior resistance against chloride stress corrosion cracking
  • Simple welding procedures
  • Machining and fabrication is difficult, due to their excellent strength
  • Outstanding tolerances in most caustic environments
  • Well suited in applications covering temperatures between -50 to 600 degrees F.

UNS S32205 Plate vs UNS S31803 Coil

  • UNS S32205 Plate is a module, which is used in applications that require high strength and durability. These plates are designed in sizes above 6mm.
  • UNS S31803 Coil is a metal component that is coiled after the initial rolling process. Available in thickness between 1.2mm to 20mm, these coils can be cut into different metal components suitable for different applications.

Duplex 2205 Plate Features

Duplex 2205 Plate is a high-strength plate having a mixture of austenitic and ferritic components. Some of the features of these plates include:

  • Excellent corrosion resistance
  • High tolerance against crevice corrosion and chloride pitting
  • Good weldability
  • Outstanding resistance against sulfide stress corrosion
  • Yield strength twice that of austenitic grades
  • Material of choice in applications requiring high strength and stability
  • Designed in sizes of above 6mm
  • Tolerances against cryogenic to high-temperature systems

ASTM A240 Type 2205 Foil Uses

ASTM A240 Type 2205 Foil is the thinnest metal component within this grade. Designed in sizes below 0.2mm, these components can be hammered or rolled. They are utilized in covering or shielding components during heat treatment and protecting them against corrosion or damage. They are widely seen in chemical and food processing, pulp mill digesters, bleach washers, heat exchanger systems, desulfurization equipment, oil fields, and so on.

Difference Between UNS S32205 Sheets and UNS S31803 Strip

UNS S32205 Sheets and UNS S31803 Strip can be distinguished based on the thickness of the gauge in the metal.

  • UNS S32205 sheets are metal components, which are less than 6mm in thickness. These sheets are employed in building structures that don’t require a lot of stability and durability.
  • UNS S31803 strip is a component that is amongst the thinnest metal item within this grade. These strips are available in sizes between 0.2mm to 0.5mm and are used in different welding processes.

Duplex Plate Vs Inconel Plate


Inconel is a family of austenitic nickel-chromium-based superalloys.

InconelElement (% by mass)

Duplex stainless steels are called “duplex” since they have a two-phase microstructure comprising of grains of ferritic and austenitic stainless steel.
