Super Duplex Stainless Steel Price Per Kg

Super Duplex Steel Price List in India (Updated 2026)

Plate cost is greatly dependent on its thickness, grade, and surface quality. Heavier gauges and tighter tolerance requirements often command a premium over standard stock sizes.

The super duplex stainless steel price rarely comes down to a single number, since it moves with product type, grade, dimensions, thickness, order quantity, and current raw material costs all at once. Two buyers asking about the same grade on the same day can still land on different quotes once these variables are factored in. Super Duplex Stainless Steel, most commonly supplied as UNS S32750 and UNS S32760, earns its premium through exceptional strength, corrosion resistance, and a service life that outlasts standard stainless steel considerably in harsh environments. That performance profile is exactly why oil & gas, offshore, marine, chemical processing, desalination, power generation, and petrochemical industries specify the material despite the higher cost per kilogram compared to standard grades. Pricing also shifts depending on product form, whether the requirement is sheets, plates, coils, pipes, bars, fittings, or flanges, since each form carries its own processing and mill cost structure. Buyers comparing the super duplex stainless steel price per kg across product types should factor in these variables before comparing quotes directly, since a lower per-kg figure on one form doesn't always translate to a lower total project cost once processing and finishing are taken into account.

Pricing is based on diameter and length. Final quoted pricing may be affected by custom cut lengths or tighter dimensional specifications.

Super Duplex Steel Pipes Price List in India

The price of pipe is based on nominal size, wall thickness and whether the pipe is seamless or welded, with seamless construction usually costing more.

Average Super Duplex pipe price in India: ~₹666/kg (~$8.10/kg).

Super Duplex Steel Fittings Price List in India (ASTM A815)

The price depends on the type, elbow, tee, reducer, or cap, as well as the size and pressure class, because each of them requires separate forging and machining labor.

Super Duplex Steel Flanges Price List in India

Flange prices depend on the pressure class, face type and size. The greater the pressure class and the larger the diameter, the higher the price per kilogram.

Note: Prices shown are indicative market ranges for September 2026 based on current FOB mill prices and Indian distributor quotations. Final pricing depends on exact grade (S32750 vs S32760), dimensions (thickness, diameter, length), finish (2B, BA, No.4, 8K), quantity (spot vs bulk), delivery location (ex-works Mumbai/Chennai vs FOB China), and current nickel/molybdenum alloy surcharges. For project-specific quotations, suppliers require grade, product form, dimensions, quantity, and delivery terms. Super Duplex 2507 typically trades at 1.5–2× the price of standard Duplex 2205 due to higher Cr (25%), Ni (7%), Mo (4%), and N (0.27%) content.
