Duplex stainless steel off-cuts
Duplex stainless steel mixes austenitic and ferritic structures in one material — roughly twice the yield strength of 316L, with much better resistance to chloride stress-corrosion cracking. Grade 2205 is the workhorse, and most pieces here are certified surplus from UAE oil, gas and water projects.

Subject to Prior Sale and Final Availability Confirmation.
The strength story is what sells duplex: because yield is about double that of 316L, designers specify thinner walls and lighter sections for the same duty. In the Gulf, that pairs with the chloride story — desalination, seawater cooling and produced-water service are exactly the environments duplex was built for.
Duplex is expensive at the mill and slow to source in small quantities, which makes certified surplus genuinely useful: project-grade material, already in the country, at off-cut prices. Welding needs a qualified procedure to keep the phase balance right — worth planning before you buy.
Common grades in this family: 2205 · UNS S32205 · UNS S31803
Common questions
When should I use duplex instead of 316L?
When strength or chlorides push 316L past its comfort zone — seawater systems, desalination plant, pressure parts you want thinner and lighter. For general architectural or food-contact work, 316L remains the economical choice.
Is duplex hard to weld?
Not hard, but particular: heat input and interpass temperature control the austenite–ferrite balance, so use a qualified procedure and matching consumables. Fabricators who work duplex regularly treat it as routine.
Why buy duplex as off-cuts?
Mill orders carry minimum quantities and long lead times, and duplex prices make full plates a serious commitment. Surplus pieces already in the UAE close that gap for repairs, spools and small fabrications.
