What is S82011?
S82011 (1.4482) is a lean duplex stainless steel with roughly 20.5–23.5% Cr, 4–6% Mn, low nickel and nitrogen strengthening, positioned as an economy alternative to 2205 for moderately corrosive structural and tank service. In the annealed condition it holds 520 MPa yield and 700 MPa tensile with 32% elongation and about 230 HB (20 HRC, 98 HRB), and is stocked as 1D and 2B sheet, hot-rolled annealed and cold-drawn bar, quarter-hard strip and welded tube. Corrosion resistance is rated 58/100 and maximum service temperature is 280 °C, both below 2205, and machinability is low at 35; move to S32205 where chloride loading or pitting risk is severe. S82011 has a density of 7.75 g/cm³ (0.28 lb/in³), lighter than 65% of stainless steel grades. It melts at 1,400°C (2,552 °F). S82011 has a yield strength of 520 MPa (75.4 ksi) and a tensile strength of 700 MPa (102 ksi) — stronger than 79% of stainless steel grades. Elongation at break is 32% and the elastic modulus is 200 GPa (29 Msi).

Working with S82011
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.
S82011 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.

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 — frequently asked
What is S82011 used for?
S82011 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?
S82011 has a typical yield strength of 520 MPa (75.4 ksi) and a tensile strength of 700 MPa (102 ksi) — stronger than 79% of stainless steel grades. Strength varies by condition: see the 3 listed tempers.
Is S82011 easy to machine?
Not especially — machinability is rated fair (35/100, better than 51% 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 be welded?
Yes — weldability is rated very good (70/100). 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 is the maximum service temperature of S82011?
S82011 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.
