Working with S82011-CD
Is S82011 easy to machine?
Machine like 2205 but at ~20–30 % lower speed than 316: rigid setups, positive-rake coated carbide, heavy constant feed to cut under the work-hardened skin, and copious coolant.
Can S82011 be welded?
GTAW/GMAW/SMAW/SAW all usable with 2209 or matching lean-duplex filler and Ar+2%N₂ shielding; keep heat input ~0.5–2.5 kJ/mm, interpass <150 °C, no preheat and no PWHT, and check ferrite 35–65 %.
Can S82011 be formed, bent or molded?
Cold form with ~2× the press force of 304 and allow for large springback; hot form 950–1150 °C followed by full solution anneal and water quench — never finish in the 300–1000 °C embrittlement range.
What surface finishes work on S82011?
Pickle and passivate (HNO₃–HF) or bead-blast plus passivation after welding to restore the passive film; electropolishing gives the best cleanability, and it is not anodisable.

S82011-CD — frequently asked
What is S82011-CD used for?
S82011-CD is typically used for pressure vessels, storage tanks, pulp & paper equipment and structural framing. In short: economy lean duplex; low-nickel 2205 alternative; 520 MPa annealed yield.
What is the yield strength of S82011-CD?
S82011-CD has a typical yield strength of 700 MPa (102 ksi) and a tensile strength of 860 MPa (125 ksi) — stronger than 92% of stainless steel grades. Strength varies by condition: see the 3 listed tempers.
Is S82011-CD easy to machine?
Not especially — machinability is rated fair (40/100, better than 72% of stainless steel grades). Machine like 2205 but at ~20–30 % lower speed than 316: rigid setups, positive-rake coated carbide, heavy constant feed to cut under the work-hardened skin, and copious coolant.
Can S82011-CD be welded?
Yes — weldability is rated good (66/100). GTAW/GMAW/SMAW/SAW all usable with 2209 or matching lean-duplex filler and Ar+2%N₂ shielding; keep heat input ~0.5–2.5 kJ/mm, interpass <150 °C, no preheat and no PWHT, and check ferrite 35–65 %.
What surface finishes work on S82011-CD?
Pickle and passivate (HNO₃–HF) or bead-blast plus passivation after welding to restore the passive film; electropolishing gives the best cleanability, and it is not anodisable.
Can S82011-CD be formed, bent or molded?
Cold form with ~2× the press force of 304 and allow for large springback; hot form 950–1150 °C followed by full solution anneal and water quench — never finish in the 300–1000 °C embrittlement range.
What is the maximum service temperature of S82011-CD?
S82011-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 S82011 Annealed and S82011-CD?
Annealed is the default condition — standard supply condition for plate, sheet, welded tube and vessels; balanced ferrite/austenite with best corrosion resistance and toughness. CD: pick for higher strength, closer tolerance and better surface on small-diameter bar and wire; ductility and toughness reduced. Yield strength is 520 MPa in Annealed versus 700 MPa in CD.
