Stainless Steel 904L Annealed vs 904L Cold Drawn
Stainless Steel · 904L temper comparison
904L Annealed and 904L Cold Drawn are two conditions of the same stainless steel grade, 904L: Annealed versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. 904L Cold Drawn is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 240 MPa (34.8 ksi) for 904L Annealed, about 129% more; tensile strength follows at 750 MPa (109 ksi) vs 560 MPa (81.2 ksi). In exchange, 904L Annealed is the more ductile: elongation 45% versus 25% for 904L Cold Drawn, and 904L Cold Drawn is harder (230 HB vs 150 HB).
904L AnnealedChoose it when the part is bent, formed or impact-loaded.
904L Cold DrawnChoose it when strength drives the design.
904L Annealed vs 904L 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.

904L Annealed vs 904L Cold Drawn — frequently asked
Is 904L Cold Drawn stronger than 904L Annealed?
Yes. 904L Cold Drawn has a typical yield strength of 550 MPa (79.8 ksi) against 240 MPa (34.8 ksi) for 904L Annealed — about 129% more. Tensile strength is 750 MPa (109 ksi) vs 560 MPa (81.2 ksi).
Which condition does FabDigit quote by default, Annealed or Cold Drawn?
Solution Annealed is the default 904L 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 904L Annealed over 904L Cold Drawn?
Pick 904L Annealed when the part is bent, formed or impact-loaded. Pick 904L Cold Drawn when strength drives the design.
