Elevate your projects with SS Duplex 2205 Coils from Salem Stainless Steel Suppliers Pvt. Ltd., your trusted primary creator, exporter, and supplier in Chennai. As the most widely used duplex stainless steel grade (also known as Duplex 2205 or S32205/S31803), our Stainless Steel Duplex 2205 Coils deliver exceptional corrosion resistance, superior strength, and cost-effective performance for demanding applications in oil & gas, chemical processing, marine, and structural engineering.
Duplex 2205 coils contain approximately 22% chromium, 3% molybdenum, and 5-6% nickel, providing outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. Due to their high yield strength almost double that of conventional austenitic stainless steels-SS Duplex 2205 Coils allow for reduced material thickness, resulting in significant cost savings for end users.
We offer SS Duplex 2205 coils in a wide range of thicknesses, widths, surface finishes, and customized specifications to meet the exact requirements of diverse industrial applications. Each coil undergoes rigorous quality checks, including chemical composition analysis, mechanical testing, and dimensional inspection, ensuring consistent performance even in aggressive environments.
