Duplex S31803 plates are manufactured from duplex stainless steel containing roughly 22% chromium, 5% nickel and 3% molybdenum. They comply with ASTM A240 and ASME SA240 specifications and are supplied in both hot‑rolled and cold‑rolled conditions. Thicknesses range from 0.1 mm to 12 mm, while standard sheet dimensions include 1220 × 2440 mm and 1500 × 3000 mm. Additional coil widths from 1000 mm up to 3000 mm are offered, with surface finishes such as 2B, 2D, BA and mirror.
Typical duplex plates exhibit a minimum tensile strength of about 620 MPa and a yield strength near 450 MPa, outperforming 304L and 316L grades in chloride environments. The alloy’s PREN value of around 40 provides resistance to pitting and stress‑corrosion cracking. Standard industry practice includes a surface roughness Ra ≤ 0.8 µm for 2B finishes and allows for finishing processes like sandblasting or brushing on request.
These plates are commonly specified for offshore platform decks, marine hulls and chemical processing equipment where both strength and corrosion resistance are critical. Prospective buyers should request mill test reports, chemical analysis certificates and dimensional inspection reports before finalising a purchase. Details on minimum order quantities, lead times and preferred Incoterms are not listed and must be obtained directly from Bhagyalaxmi Industrial.

Prior to ordering, obtain the current mill test report, a full chemical analysis certificate and a dimensional inspection report for the plates. Confirm that the documentation references the exact sheet size, thickness and surface finish you require, and that the material grade matches UNS S31803.
Clarify the preferred Incoterms, freight method and packaging style with the supplier. Plates can be shipped as flat sheets, coiled material or cut to size, and freight costs will vary accordingly. Lead times are not stated in the listing; request an estimated production and shipping schedule to align with your project timeline.
Arrange for third‑party inspection or non‑destructive testing such as ultrasonic thickness measurement, especially for critical structural applications. Ensure the supplier can provide inspection certificates and that the final product meets the agreed mechanical and surface‑finish tolerances before acceptance.
