Duplex 2205 stainless steel off-cuts

The duplex structure — half austenite, half ferrite — is what buys both strength and corrosion resistance at once. A 22% chromium, 5% nickel, 3% molybdenum, nitrogen-enhanced chemistry gives a 450 MPa yield floor, so designers can halve wall thicknesses against 316L and still gain margin against chloride pitting and stress-corrosion cracking — the failure mode that retires austenitic grades in warm Gulf seawater.

The trade-off is discipline in the workshop: welding needs matched consumables and controlled heat input to keep the phase balance, and service above roughly 250–300 °C is off the table. Off-cuts from desalination and tank projects appear here as plate and pipe in serious sizes; every listing shows exact dimensions and price upfront.
