2205 Duplex — Machining & Properties
Typical properties, what 2205 Duplex is like on a machine tool, what it gets used for, and the tolerance and finishes we hold on it — from a shop that actually machines it, not a datasheet aggregator. Every figure here drives our own calculators.
Machining 2205 Duplex
Machinability is rated difficult — a genuinely demanding material — rigid setups, premium tooling and conservative parameters, with cycle time and tool wear to match. Austenitic grades (303, 304, 316) work-harden during cutting. Sharp tooling, correct feeds and speeds, and no dwelling are essential. Martensitic and PH grades should be machined in the annealed condition where possible, with final heat treatment applied post-machining to minimise distortion.
Our standard achievable tolerance on 2205 Duplex is ±0.020mm under normal conditions, with tighter tolerances on critical features agreed at quotation. Standard finishes: As machined, passivation. Full material traceability with MTR and CoC documentation on every order.
Typical applications
Marine, oil & gas, subsea pressure vessels and pipework.

2205 Duplex — FAQ
What is the density of 2205 Duplex?
7.82 g/cm³ (typical). That is 7820 kg/m³ — our metal weight calculator uses exactly this figure for 2205 Duplex.
What is the tensile strength of 2205 Duplex?
Typically 620 MPa. Treat it as a typical value, not a specification — the Material Test Report supplied with your order states the actual certified figures for the batch.
Is 2205 Duplex easy to machine?
Its machinability is rated difficult — a genuinely demanding material — rigid setups, premium tooling and conservative parameters, with cycle time and tool wear to match.
What is 2205 Duplex used for?
Typical applications: Marine, oil & gas, subsea pressure vessels and pipework.
What tolerance can be held when machining 2205 Duplex?
Our standard achievable tolerance on 2205 Duplex is ±0.020mm under normal conditions (ISO 2768-f general tolerancing). Tighter tolerances on critical features can be agreed at quotation for specific geometries.
Can Dalloway machine 2205 Duplex?
Yes — we machine 2205 Duplex in-house on 3, 4 and 5-axis milling and CNC turning, from single prototypes to production, with MTR and CoC documentation standard. Typical finishes: As machined, passivation.
