Product information for purchasing teams
Duplex 2205 has a mixed austenite-ferrite structure. It is roughly twice as strong as 316L, resists chloride stress-corrosion cracking far better, and has higher pitting resistance, so thinner walls can often replace 316L in offshore, desalination and chemical service.
Exact specification, availability and commercial details are confirmed against your enquiry.

Questions buyers ask
What is the difference between S31803 and S32205?
S32205 is a tighter version of S31803 with higher minimum chromium, molybdenum and nitrogen. Most mills now dual-certify to both, but state which one your specification requires.
Which standard covers Duplex 2205 Plates?
Duplex 2205 Plates are supplied to ASTM A240 / ASME SA240 UNS S32205.
