Working with S32205-CD
Is S32205 easy to machine?
Cuts like a work-hardening, high-strength stainless: use rigid setups, ~60–70% of 316L speeds, heavy positive feed to stay under the hardened skin, sharp coated carbide and copious coolant.
Can S32205 be welded?
Readily welded by GTAW/GMAW/SMAW with over-alloyed 2209/E2209 filler; keep heat input roughly 0.5–2.5 kJ/mm and interpass below 150 °C, avoid autogenous welds without post-weld anneal to preserve 50/50 ferrite-austenite.
Can S32205 be formed, bent or molded?
Cold forming needs roughly twice the force of 304 with large springback allowance; hot form at 1000–1200 °C followed by full solution anneal and quench — never finish between 300 and 950 °C.
What surface finishes work on S32205?
Pickle and passivate (HNO₃-HF) after welding or use mechanical descaling then passivation; electropolishing gives the best pitting performance; not anodizable.

S32205-CD — frequently asked
What is S32205-CD used for?
S32205-CD is typically used for oil and gas piping, chemical process vessels, desalination equipment and marine structures. In short: standard workhorse duplex; double the yield of 316L; chloride SCC resistant.
What is the yield strength of S32205-CD?
S32205-CD has a typical yield strength of 700 MPa (102 ksi) and a tensile strength of 880 MPa (128 ksi) — stronger than 92% of stainless steel grades. Strength varies by condition: see the 4 listed tempers.
Is S32205-CD easy to machine?
Not especially — machinability is rated poor (32/100, worse than 62% of stainless steel grades). Cuts like a work-hardening, high-strength stainless: use rigid setups, ~60–70% of 316L speeds, heavy positive feed to stay under the hardened skin, sharp coated carbide and copious coolant.
Can S32205-CD be welded?
Yes — weldability is rated good (65/100). Readily welded by GTAW/GMAW/SMAW with over-alloyed 2209/E2209 filler; keep heat input roughly 0.5–2.5 kJ/mm and interpass below 150 °C, avoid autogenous welds without post-weld anneal to preserve 50/50 ferrite-austenite.
What surface finishes work on S32205-CD?

Cold forming needs roughly twice the force of 304 with large springback allowance; hot form at 1000–1200 °C followed by full solution anneal and quench — never finish between 300 and 950 °C.
What is the maximum service temperature of S32205-CD?
S32205-CD is rated for continuous use to about 280°C (536 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between S32205-SA and S32205-CW?
SA is the default condition — standard supply condition for plate, sheet, pipe and bar — best combination of corrosion resistance and toughness. CW: springs, wire rope and fasteners where strength matters more than toughness or formability. Yield strength is 550 MPa in SA versus 950 MPa in CW.
