Working with S32202 Annealed
Is S32202 easy to machine?
Machine like 2205 but with ~20–30% lower cutting speeds than 304: rigid setups, sharp coated carbide, heavy positive feeds to cut under the work-hardened layer, and copious coolant.
Can S32202 be welded?
Weldable by GTAW/GMAW/SMAW/SAW with 2209 or 2307-type filler (autogenous welding only with N₂-bearing shielding plus a re-anneal); keep heat input roughly 0.2–1.5 kJ/mm and interpass below ~150 °C to hold 30–70% ferrite.
Can S32202 be formed, bent or molded?
Cold formable but needs ~2× the press force and larger bend allowances than 304 due to high yield strength and springback; hot form at 950–1150 °C followed by full solution anneal and water quench.
What surface finishes work on S32202?
Pickle and passivate after hot work or welding to restore the passive film; takes standard 2B/BA/No.4 and mirror polishes, and is readily electropolished.
S32202 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

S32202 Annealed — frequently asked
What is S32202 Annealed used for?
S32202 Annealed is typically used for structural pipe, tanks and architectural panels. In short: molybdenum-free lean duplex; between 2101 and 2304; high strength, moderate corrosion.
What is the yield strength of S32202 Annealed?
S32202 Annealed has a typical yield strength of 520 MPa (75.4 ksi) and a tensile strength of 750 MPa (109 ksi) — stronger than 79% of stainless steel grades. Strength varies by condition: see the 3 listed tempers.
Is S32202 Annealed easy to machine?
Not especially — machinability is rated fair (35/100, better than 51% of stainless steel grades). Machine like 2205 but with ~20–30% lower cutting speeds than 304: rigid setups, sharp coated carbide, heavy positive feeds to cut under the work-hardened layer, and copious coolant.
Can S32202 Annealed be welded?
Yes — weldability is rated very good (70/100). Weldable by GTAW/GMAW/SMAW/SAW with 2209 or 2307-type filler (autogenous welding only with N₂-bearing shielding plus a re-anneal); keep heat input roughly 0.2–1.5 kJ/mm and interpass below ~150 °C to hold 30–70% ferrite.
What surface finishes work on S32202 Annealed?
Pickle and passivate after hot work or welding to restore the passive film; takes standard 2B/BA/No.4 and mirror polishes, and is readily electropolished.
Can S32202 Annealed be formed, bent or molded?
Cold formable but needs ~2× the press force and larger bend allowances than 304 due to high yield strength and springback; hot form at 950–1150 °C followed by full solution anneal and water quench.
What is the maximum service temperature of S32202 Annealed?
S32202 Annealed 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 S32202 Annealed and S32202-CD?
Annealed is the default condition — standard stocked condition for sheet, coil and strip; best combination of strength, ductility and corrosion resistance. CD: pick when tighter tolerances, straightness and higher yield strength are needed; ductility and formability drop. Yield strength is 520 MPa in Annealed versus 680 MPa in CD.
