Stainless Steel 904L Annealed vs 904L Solution Annealed
Stainless Steel · 904L temper comparison
904L Annealed and 904L Solution Annealed are two conditions of the same stainless steel grade, 904L: Annealed versus Solution Annealed. The chemistry is identical, so every difference below comes from the condition. 904L Solution Annealed is the stronger of the two: yield strength 260 MPa (37.7 ksi) against 240 MPa (34.8 ksi) for 904L Annealed, about 8% more; tensile strength follows at 590 MPa (85.6 ksi) vs 560 MPa (81.2 ksi).

904L Annealed vs 904L Solution Annealed: 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.
