This series of 2205 duplex seamless hollow bars are manufactured via hot extrusion + cold drawing forming process. After strict 1020–1100℃ solution annealing followed by rapid water quenching, the material forms uniform dual-phase austenite-ferrite grain structure without harmful intermetallic precipitates.
2205 is the most widely used standard duplex stainless steel grade. It combines high mechanical strength and outstanding chloride corrosion resistance, filling the performance gap between ordinary austenitic stainless steel and expensive super duplex grades. Seamless hollow bar blanks save massive solid bar boring workload, widely machined into heat exchanger tubes, offshore tubular fittings, desalination pipeline sleeves and sour gas downhole components for marine, chemical, pulp & paper and oil & gas industries.

| Property | 2205 Duplex Hollow Bar |
|---|---|
| Delivery Condition | Hot Extruded, Solution Annealed, Water Quenched, Stress‑Relieved, Pickled |
| Minimum Tensile Strength | ≥655 MPa (95 ksi) |
| Minimum 0.2% Yield Strength | ≥450 MPa (65 ksi) |
| Minimum Elongation (50mm gauge) | ≥25 % |
| Maximum Brinell Hardness | ≤293 HB |
450MPa minimum yield strength enables thinner wall hollow design, reduces raw material consumption and overall equipment weight.
High PREN index resists seawater pitting, crevice and stress cracking, far superior to 316L in marine & desalination environments.
Passes NACE standard test, reliable for H₂S-containing oil & gas downhole tubular service.
Low carbon formula prevents intergranular corrosion; no post heat treatment needed after welding with controlled heat input.
Ready extruded hollow blank eliminates deep boring on solid bar, shortens CNC processing cycle and lowers machining cost.
We provide integrated hot extrusion & cold drawing production, full precision machining per customer CAD/PDF drawings:
We supply 2205 duplex hollow blanks, heat exchanger tubes, valve sleeves and tubular fittings for marine, chemical and energy global clients.
Mill Test Certificate EN 10204 3.1 can be issued and attached with shipment documents.
- Inner: Plastic end caps + waterproof anti-rust polybag to protect inner bore & outer surface
- Outer: Reinforced fumigated wooden case with separate partition to avoid tube collision
- Custom heavy-duty export packaging available on request
Normally 10 – 45 working days after advance payment receipt. Lead time varies based on tube OD/ID wall size, order quantity and custom machining demands.
