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.
