Stainless Steel 304L Annealed vs 304L Cold Drawn
Stainless Steel · 304L temper comparison
304L Annealed and 304L Cold Drawn are two conditions of the same stainless steel grade, 304L: Annealed versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. 304L Cold Drawn is the stronger of the two: yield strength 500 MPa (72.5 ksi) against 275 MPa (39.9 ksi) for 304L Annealed, about 82% more; tensile strength follows at 700 MPa (102 ksi) vs 585 MPa (84.8 ksi). In exchange, 304L Annealed is the more ductile: elongation 55% versus 30% for 304L Cold Drawn, and 304L Cold Drawn is harder (215 HB vs 150 HB).
304L AnnealedChoose it when the part is bent, formed or impact-loaded.
304L Cold DrawnChoose it when strength drives the design.
304L Annealed vs 304L 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.
