What is Duplex Plate?

A Duplex Plate is a metal plate manufactured from a unique alloy composition typically comprising iron, nickel, chromium, and sometimes other elements like molybdenum and nitrogen. What sets Duplex Plates apart is their two-phase microstructure at room temperature, which seamlessly blends the characteristics of ferritic and austenitic stainless steels.

These plates find extensive use across various industries where high-performance materials are required, such as chemical processing, oil and gas exploration, marine engineering, and structural applications. They are sought after for their ability to withstand harsh environments, resist corrosion, and maintain structural integrity under extreme conditions.

What are the different grades of Duplex Plate?

  • Duplex Stainless Steel 2205 (UNS S31803/S32205) is the most widely used duplex stainless steel grade. It offers good corrosion resistance, high strength, and excellent weldability.
  • Duplex Stainless Steel 2304 (UNS S32304): This grade has a lower alloy content than 2205, offering good corrosion resistance in mild environments and higher strength than austenitic stainless steel.
  • Duplex Stainless Steel 2507 (UNS S32750): Also known as super duplex stainless steel, this grade offers superior corrosion resistance, particularly in aggressive environments such as seawater and chemical processing applications. It has high strength and excellent resistance to pitting and crevice corrosion.
  • Duplex Stainless Steel LDX 2101 (UNS S32101): This grade offers a combination of high strength, good corrosion resistance, and low nickel content for cost-effective solutions in various applications.
  • Duplex Stainless Steel 2102 (UNS S32101): Similar to LDX 2101, this grade offers good strength and corrosion resistance properties with a lower nickel content.

How to prevent corrosion in Duplex Plates?

  • Preventing corrosion in Duplex Plates involves implementing proactive measures and best practices tailored to the specific operating conditions and environmental factors. Firstly, thorough material selection is crucial, ensuring the duplex grade chosen aligns with the anticipated corrosive environment.
  • Regular inspections and assessments of the operating conditions help identify potential corrosion risks early on. Employing corrosion-resistant coatings or inhibitors can provide additional protection against corrosive agents. Proper design considerations, such as avoiding crevices and ensuring adequate drainage, help mitigate areas prone to corrosion accumulation.
  • Implementing effective cathodic protection systems can also safeguard Duplex Plates from corrosion by controlling the electrochemical reactions that lead to degradation. Routine maintenance, including cleaning and surface treatments, further extends the longevity of Duplex Plates by removing contaminants and restoring protective surface layers.

Manufacturing Process of Duplex Plates

Duplex Plate is produced in seven steps. It manufactures a wide range of shapes, goods, and parts, ranging from Duplex Plate and Coil.

  • Step 1 : Raw Material Selection
    To begin the process of creating Duplex, raw materials such as iron ore and other elements including nickel, chromium, and molybdenum are carefully selected. The choice of alloying elements depends on the specific properties that the Duplex is intended to possess.
  • Step 2 : Smelting and Melting
    Once the raw materials have been selected, they are smelted in a furnace to create a molten metal alloy. The composition of the alloy is closely monitored and controlled to achieve the desired grade of Duplex.
  • Step 3 : Forming
    After the molten Duplex has been produced, it is cast into different shapes and forms, depending on its intended use. The most common shapes include slabs, billets, blooms, or ingots.
  • Step 4 : Primary & Secondary Steelmaking
    The subsequent step is primary steelmaking, which can be accomplished through different methods such as the Basic Oxygen Furnace (BOF) or the Electric Arc Furnace (EAF). At this stage, impurities like carbon are eliminated to achieve the desired chemical composition.
  • Step 5 : Casting
    The molten Duplex is then cast into semi-finished forms, which can take the shape of plates, sheets, bars, or other forms. Continuous casting or ingot casting methods are usually employed for this purpose.
  • Step 6 : Hot Rolling
    In the case of products like Duplex Plates, the semi-finished castings are hot-rolled to achieve the desired thickness and shape. During this process, the thickness of the castings is reduced while improving their mechanical properties.
  • Step 7 : Cold Rolling and Annealing
    In the case of specific Duplex products such as thin sheets and coils, cold rolling is employed to further reduce the thickness and enhance surface finish. To relieve stresses and enhance corrosion resistance, annealing is frequently performed.
