Stainless Steel 310S Annealed vs 310S Cold Drawn
Stainless Steel · 310S temper comparison
310S Annealed and 310S Cold Drawn are two conditions of the same stainless steel grade, 310S: Annealed versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. 310S Cold Drawn is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 255 MPa (37 ksi) for 310S Annealed, about 104% more; tensile strength follows at 760 MPa (110 ksi) vs 570 MPa (82.7 ksi). In exchange, 310S Annealed is the more ductile: elongation 45% versus 25% for 310S Cold Drawn, and 310S Cold Drawn is harder (230 HB vs 170 HB).
310S AnnealedChoose it when the part is bent, formed or impact-loaded.
310S Cold DrawnChoose it when strength drives the design.
310S Annealed vs 310S 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.

310S Annealed vs 310S Cold Drawn — frequently asked
Is 310S Cold Drawn stronger than 310S Annealed?
Yes. 310S Cold Drawn has a typical yield strength of 520 MPa (75.4 ksi) against 255 MPa (37 ksi) for 310S Annealed — about 104% more. Tensile strength is 760 MPa (110 ksi) vs 570 MPa (82.7 ksi).
Which condition does FabDigit quote by default, Annealed or Cold Drawn?
Solution Annealed is the default 310S condition in the FabDigit quote flow (neither Annealed nor Cold Drawn). 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.
When should I choose 310S Annealed over 310S Cold Drawn?
Pick 310S Annealed when the part is bent, formed or impact-loaded. Pick 310S Cold Drawn when strength drives the design.
