Short answer: HXSCO supplies duplex stainless steel in 2205, 2507 and lean duplex plate, sheet, bar and pipe, combining roughly twice the strength of 304 with strong chloride corrosion resistance, for offshore, desalination, chemical and structural duty, with mill certificate and moisture-safe export packing.
At a Glance
Our Duplex Range
Duplex stainless sits beside our Stainless Steel Supplier line, with chemistry detailed on our Duplex 2205 Stainless Steel page; the grade family is compared with austenitic options in our 304 vs 316 Stainless Steel guide and the plate forms in our Chapa de aço inoxidável 304 e Chapa de aço inoxidável 316 pages.
Strength and Corrosion Profile
Duplex carries about double the yield strength of 304/316 and resists chloride pitting and stress corrosion cracking far better than austenitic grades; the corrosion science is in our Corrosion Resistance Guide, the marine angle in our Metal for Marine and Offshore Guide and the chemical angle in our Metal for Chemical Processing Guide.
Welding, Finish and Packing
Duplex needs controlled heat input and filler selection, detailed in our Stainless Steel Welding Guide e Welding Joining Guide; surface prep is in our Surface Treatment Guide, certification in our Mill Test Certificate Guide and export packing in our Export Packing Guide.
Aplicativos
2205 serves heat exchangers, tanks and bridges, 2507 serves seawater and desalination, and lean duplex serves structural and rail; the structure story is in our Bridges and Infrastructure Guide and the cost view in our Stainless Steel Price Factors page, while the coating comparison is in our Galvanized vs Stainless guide.

2205 and 2507 as core grades, plus lean duplex 2304 and LDX 2101 for structural duty.
Yes – duplex yields roughly twice the strength of 316 at similar corrosion resistance in chloride service.
It welds with controlled heat input and matching duplex filler; see our welding guides for parameters.
2507 super duplex is chosen for seawater, desalination and subsea where pitting resistance matters most.
Bundled, interleaved and wrapped moisture-safe, with EN 10204 3.1 mill certificate.
