Working with S82013-SA
Is S82013 easy to machine?
Machine like 2205: rigid setups, 20–30% lower surface speed than 304, positive-rake coated carbide, heavy constant feed and copious coolant to avoid work hardening and built-up edge.
Can S82013 be welded?
Weldable by GTAW/GMAW/SMAW with over-alloyed 2209-type or matching lean-duplex filler and Ar+2%N shielding; keep heat input moderate (≈0.5–1.5 kJ/mm), interpass <150 °C, no post-weld heat treatment unless full solution anneal + quench is possible.
Can S82013 be formed, bent or molded?
Cold forms well but needs ~2× the press force of 304 with large springback allowance; hot work 950–1150 °C followed by solution anneal and rapid water quench to restore the 50/50 phase balance.
What surface finishes work on S82013?
Pickle and passivate (or electropolish) after hot work and welding to remove heat tint; not anodisable — mechanical polish, bead blast or brushed 2B/No.4 finishes are standard.

S82013-SA — frequently asked
What is S82013-SA used for?
S82013-SA is typically used for forgings, bar stock, structural fittings and tank components. In short: forging-grade lean duplex; 540 MPa annealed yield; low-nickel duplex family.
What is the yield strength of S82013-SA?
S82013-SA has a typical yield strength of 540 MPa (78.3 ksi) and a tensile strength of 730 MPa (106 ksi) — stronger than 82% of stainless steel grades. Strength varies by condition: see the 4 listed tempers.
Is S82013-SA easy to machine?
Not especially — machinability is rated fair (35/100, better than 51% of stainless steel grades). Machine like 2205: rigid setups, 20–30% lower surface speed than 304, positive-rake coated carbide, heavy constant feed and copious coolant to avoid work hardening and built-up edge.
Can S82013-SA be welded?
Yes — weldability is rated good (65/100). Weldable by GTAW/GMAW/SMAW with over-alloyed 2209-type or matching lean-duplex filler and Ar+2%N shielding; keep heat input moderate (≈0.5–1.5 kJ/mm), interpass <150 °C, no post-weld heat treatment unless full solution anneal + quench is possible.
What surface finishes work on S82013-SA?
Pickle and passivate (or electropolish) after hot work and welding to remove heat tint; not anodisable — mechanical polish, bead blast or brushed 2B/No.4 finishes are standard.
Can S82013-SA be formed, bent or molded?
Cold forms well but needs ~2× the press force of 304 with large springback allowance; hot work 950–1150 °C followed by solution anneal and rapid water quench to restore the 50/50 phase balance.
What is the maximum service temperature of S82013-SA?
S82013-SA 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 S82013-SA and S82013-CD?
SA is the default condition — default stocked condition for plate, sheet and coil: ~50/50 ferrite/austenite, best combination of strength, ductility and corrosion resistance. CD: pick for higher proof strength, straightness and a bright ground/turned surface on small-diameter bar and wire stock. Yield strength is 540 MPa in SA versus 720 MPa in CD.
