Stainless Steel 304H Annealed vs 304H Cold Drawn
Stainless Steel · 304H temper comparison
304H Annealed and 304H Cold Drawn are two conditions of the same stainless steel grade, 304H: Annealed versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. 304H Cold Drawn is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 265 MPa (38.4 ksi) for 304H Annealed, about 70% more; tensile strength follows at 690 MPa (100 ksi) vs 580 MPa (84.1 ksi). In exchange, 304H Annealed is the more ductile: elongation 53% versus 32% for 304H Cold Drawn, and 304H Cold Drawn is harder (210 HB vs 155 HB).
304H AnnealedChoose it when the part is bent, formed or impact-loaded.
304H Cold DrawnChoose it when strength drives the design.
304H Annealed vs 304H 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.

304H Annealed vs 304H Cold Drawn — frequently asked
Is 304H Cold Drawn stronger than 304H Annealed?
Yes. 304H Cold Drawn has a typical yield strength of 450 MPa (65.3 ksi) against 265 MPa (38.4 ksi) for 304H Annealed — about 70% more. Tensile strength is 690 MPa (100 ksi) vs 580 MPa (84.1 ksi).
Which condition does FabDigit quote by default, Annealed or Cold Drawn?
Solution Annealed is the default 304H 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.
Which is easier to machine, 304H Annealed or 304H Cold Drawn?
304H Cold Drawn, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for 304H Annealed.
