What is 2205 Cold Drawn?

2205 Cold Drawn is 2205 supplied in the Cold Drawn condition — choose for close tolerances, straightness and a strength bump in shafting, fasteners and instrument tubing. 2205 Cold Drawn has a yield strength of 650 MPa (94.3 ksi) and a tensile strength of 860 MPa (125 ksi) — stronger than 90% of stainless steel grades. Elongation at break is 22% and the elastic modulus is 200 GPa (29 Msi). 2205 Cold Drawn has a density of 7.8 g/cm³ (0.282 lb/in³), heavier than 50% of stainless steel grades. It melts at 1,385°C (2,525 °F). Solution Annealed is the default condition FabDigit quotes; Cold Drawn is available on request or by drawing note.

Working with 2205 Cold Drawn

Is 2205 easy to machine?

Machine like a high-strength austenitic but with ~30 % of 1212 speeds: rigid setups, positive-rake coated carbide, heavy constant feed, generous coolant, avoid dwelling to prevent work hardening.

Can 2205 be welded?

GTAW/GMAW/SMAW with over-alloyed 2209 filler and Ar+1–2 % N2 or Ar shielding; keep heat input ~0.5–2.5 kJ/mm and interpass <150 °C, no preheat and no PWHT (solution anneal + quench only if heat treated).

Can 2205 be formed, bent or molded?

Cold form with ~2× the force and springback of 304, generous bend radii (≥2t) and no low-temperature stress relief; hot work 1000–1200 °C with immediate solution anneal and quench.

What surface finishes work on 2205?

Pickle and passivate (HNO3-HF) after welding or grinding to restore the passive film; electropolishing and mechanical polishing to Ra <0.5 µm are routine — anodizing is not applicable.

2205 Cold Drawn — frequently asked

What is 2205 Cold Drawn used for?

2205 Cold Drawn is typically used for offshore platform piping and structures, heat exchanger tubes and plates, pressure vessels for chemical process, desalination plant components, pulp and paper digester parts and seawater pump and valve bodies. In short: acid-proof duplex stainless.

What is the yield strength of 2205 Cold Drawn?

2205 Cold Drawn has a typical yield strength of 650 MPa (94.3 ksi) and a tensile strength of 860 MPa (125 ksi) — stronger than 90% of stainless steel grades. Strength varies by condition: see the 8 listed tempers.

Is 2205 Cold Drawn easy to machine?

Not especially — machinability is rated poor (32/100, worse than 62% of stainless steel grades). Machine like a high-strength austenitic but with ~30 % of 1212 speeds: rigid setups, positive-rake coated carbide, heavy constant feed, generous coolant, avoid dwelling to prevent work hardening.

Can 2205 Cold Drawn be welded?

Yes — weldability is rated very good (78/100). GTAW/GMAW/SMAW with over-alloyed 2209 filler and Ar+1–2 % N2 or Ar shielding; keep heat input ~0.5–2.5 kJ/mm and interpass <150 °C, no preheat and no PWHT (solution anneal + quench only if heat treated).

What surface finishes work on 2205 Cold Drawn?

Pickle and passivate (HNO3-HF) after welding or grinding to restore the passive film; electropolishing and mechanical polishing to Ra <0.5 µm are routine — anodizing is not applicable.

Can 2205 Cold Drawn be formed, bent or molded?

Cold form with ~2× the force and springback of 304, generous bend radii (≥2t) and no low-temperature stress relief; hot work 1000–1200 °C with immediate solution anneal and quench.

What is the maximum service temperature of 2205 Cold Drawn?

2205 Cold Drawn is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
