Stainless Steel S32900 Annealed vs S32900 Cold Drawn
Stainless Steel · S32900 temper comparison
S32900 Annealed and S32900 Cold Drawn are two conditions of the same stainless steel grade, S32900: Annealed versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. S32900 Cold Drawn is the stronger of the two: yield strength 690 MPa (100 ksi) against 540 MPa (78.3 ksi) for S32900 Annealed, about 28% more; tensile strength follows at 830 MPa (120 ksi) vs 720 MPa (104 ksi). In exchange, S32900 Annealed is the more ductile: elongation 27% versus 18% for S32900 Cold Drawn, and S32900 Cold Drawn is harder (280 HB vs 240 HB).

S32900 Cold DrawnChoose it when strength drives the design.
S32900 Annealed vs S32900 Cold Drawn: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

S32900 Annealed vs S32900 Cold Drawn — frequently asked
Is S32900 Cold Drawn stronger than S32900 Annealed?
Yes. S32900 Cold Drawn has a typical yield strength of 690 MPa (100 ksi) against 540 MPa (78.3 ksi) for S32900 Annealed — about 28% more. Tensile strength is 830 MPa (120 ksi) vs 720 MPa (104 ksi).
Which condition does FabDigit quote by default, Annealed or Cold Drawn?
Annealed is the default S32900 condition in the FabDigit quote flow. The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, S32900 Annealed or S32900 Cold Drawn?
S32900 Cold Drawn, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for S32900 Annealed; for welding the order is S32900 Annealed first (good, 55/100) then S32900 Cold Drawn (fair, 50/100).
