Duplex Steel Plate stands out with excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. These properties make it a preferred choice for applications in environments where both chlorides and elevated temperatures are present, ensuring long-term service and reliability.
Versatile Applications and CustomizationWith a highly customizable range of dimensions and thicknesses between 3mm to 100mm, the Duplex Steel Plate supports various industrial needs. It finds extensive use in structural projects, process equipment, pressure vessels, and heat exchangers across sectors like chemical, marine, and oil & gas.
Robust Mechanical PerformanceFeaturing a minimum yield strength of 450 MPa and elongation of 25% or more, Duplex Steel Plate delivers impressive mechanical durability. Its maximum hardness of 290 HB further ensures resistance to wear and deformation, making it well-suited for heavy-duty applications.
FAQs of Duplex Steel Plate:
Q: How does the duplex microstructure affect the magnetic properties of Duplex Steel Plate?
A: Due to its duplex microstructure, the Duplex Steel Plate is slightly magnetic. This is a result of the combination of austenitic and ferritic phases in the material, which provide both excellent strength and limited magnetism compared to standard stainless steels.
Q: What welding processes can be used with Duplex Steel Plate?
A: Duplex Steel Plate offers excellent weldability and is suitable for all standard welding methods such as TIG, MIG, and arc welding. Proper precautions like controlling heat input and selecting compatible filler materials help maintain its superior mechanical and corrosion-resistant properties.
Q: When is Duplex Steel Plate recommended for use over regular stainless steel plates?
A: Duplex Steel Plate is recommended when high mechanical strength and superior corrosion resistance, especially against pitting and stress corrosion cracking, are required. It is ideal for chemical processing, marine environments, and pressure equipment where standard grades may underperform.
Q: Where can Duplex Steel Plate be supplied from in India?
A: Duplex Steel Plate is available from various Indian manufacturers, exporters, importers, and suppliers who can offer both standard and custom sizes. The product is packaged in standard export seaworthy packing for safe transportation nationally or internationally.
Q: What is the process for customizing the dimensions of Duplex Steel Plate?
A: To customize the dimensions, clients can specify their required length, width, and thickness (from 3mm to 100mm). Manufacturers process these requests and supply plates in rectangular shapes, with mill or sheared edge types, to meet diverse application needs.
Q: How is Duplex Steel Plate used in structural and process equipment?
A: Duplex Steel Plates high strength, formability, and corrosion resistance make it ideal for constructing structural frameworks, process equipment, pressure vessels, and heat exchangers. Its excellent heat resistance (up to 300C continuous) ensures reliable performance in demanding conditions.
Q: What are the key benefits of choosing Duplex Steel Plate for industrial applications?
A: Benefits include superior mechanical strength, remarkable corrosion and heat resistance, excellent weldability, and environmental sustainability due to its recyclability. Custom sizing, diverse surface finishes, and dependable export packing further enhance its appeal for critical industrial uses.
