Duplex Stainless Steel Plate
Duplex stainless steel plates represent a unique alloy, seamlessly merging the advantages of ferritic and austenitic stainless steels. This dual-phase microstructure establishes unparalleled resistance to corrosion, stress corrosion cracking, and erosion—making them indispensable in demanding settings like offshore oil rigs and chemical processing plants.
At Ashapura Steel, we present a diverse array of duplex stainless steel plate grades, including S31803, S32205, S32750, and S32760. Each grade possesses distinct mechanical properties and corrosion resistance, ensuring a tailored solution for your specific requirements.
Beyond their corrosion resistance, duplex stainless steel plates boast high strength, exceptional toughness, and favorable weldability, rendering them versatile across various applications.
Whether destined for oil and gas, chemical processing, marine engineering, or other industrial applications, Ashapura Steel caters to your needs with expertise and quality products. Our commitment extends to delivering superior products and ensuring customer satisfaction.
Types of Duplex Stainless Steel Plates
Lean Duplex Stainless Steel Plates
Lean duplex stainless steel plates have a low nickel content, which makes them more affordable than other types of duplex stainless steel plates. They contain around 17-18% chromium and 4-6% nickel, making them ideal for use in applications where corrosion resistance is required but not at high levels.
