Stainless Steel 2304 Annealed vs 2304 Cold Drawn
Stainless Steel · 2304 temper comparison
2304 Annealed and 2304 Cold Drawn are two conditions of the same stainless steel grade, 2304: Annealed versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. 2304 Cold Drawn is the stronger of the two: yield strength 650 MPa (94.3 ksi) against 455 MPa (66 ksi) for 2304 Annealed, about 43% more; tensile strength follows at 850 MPa (123 ksi) vs 680 MPa (98.6 ksi). In exchange, 2304 Annealed is the more ductile: elongation 30% versus 20% for 2304 Cold Drawn, and 2304 Cold Drawn is harder (280 HB vs 240 HB).
2304 AnnealedChoose it when the part is bent, formed or impact-loaded.
2304 Cold DrawnChoose it when strength drives the design.
2304 Annealed vs 2304 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.

2304 Annealed vs 2304 Cold Drawn — frequently asked
Is 2304 Cold Drawn stronger than 2304 Annealed?
Yes. 2304 Cold Drawn has a typical yield strength of 650 MPa (94.3 ksi) against 455 MPa (66 ksi) for 2304 Annealed — about 43% more. Tensile strength is 850 MPa (123 ksi) vs 680 MPa (98.6 ksi).
Which condition does FabDigit quote by default, Annealed or Cold Drawn?
Solution Annealed is the default 2304 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 2304 Annealed over 2304 Cold Drawn?
Pick 2304 Annealed when the part is bent, formed or impact-loaded. Pick 2304 Cold Drawn when strength drives the design.
