Short answer: HXSCO supplies duplex stainless steel — 2205, 2507, 2304 and lean duplex — in plate, pipe, bar and fittings, delivering roughly twice the strength of 316L with far better chloride pitting and stress-corrosion resistance for offshore, chemical and desalination service.
At a Glance
Duplex Grades We Supply
Duplex stainless is a balanced austenite-ferrite microstructure that roughly doubles the yield strength of 316L while resisting chloride attack. The metallurgy is covered in Duplex Stainless Steel Guide, grade data in Duplex 2205 Properties Guide and the super-duplex step-up in Duplex Vs Super Duplex. It sits between our Stainless Steel Supplier 300-series range and Nickel Alloy Supplier grades on cost and performance.
Forms, Fabrication & Limits
We ship duplex plate, sheet, seamless and welded pipe, bar, flanges and fittings. Fabrication demands discipline: keep heat input controlled to hold the phase balance, avoid long exposure between 300–1000 °C, and pickle or passivate afterwards per Passivation Vs Pickling. Welding practice follows How To Weld Stainless Steel with matching consumables per Welding Consumables Guide.
Applications & Quality
Duplex serves offshore and subsea, desalination, chemical and pulp plant, chloride-bearing tanks, bridges and pressure vessels — anywhere Pitting Corrosion Stainless Steel e Stress Corrosion Cracking rule out standard austenitics. Every lot ships with a mill certificate per Mill Test Certificate Guide, PMI and ferrite-content checks on request.

Domande frequenti
HXSCO supplies 2205 (S32205), 2507 super duplex (S32750), 2304 and lean duplex S32101 in plate, pipe, bar, flanges and fittings.
Yes. Duplex 2205 has roughly twice the yield strength of 316L, which often allows thinner, lighter sections at similar or better corrosion resistance.
PREN is the pitting resistance equivalent number from chromium, molybdenum and nitrogen content; 2205 is around 35 and 2507 super duplex around 42.
Yes. Every duplex lot ships with an EN 10204 mill certificate, and PMI or ferrite-content verification on request.
