Stainless Steel 904L Annealed vs 904L Cold Rolled Hard
Stainless Steel · 904L temper comparison
904L Annealed and 904L Cold Rolled Hard are two conditions of the same stainless steel grade, 904L: Annealed versus Cold Rolled Hard (cold rolled strip/sheet, temper rolled). The chemistry is identical, so every difference below comes from the condition. 904L Cold Rolled Hard is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 240 MPa (34.8 ksi) for 904L Annealed, about 158% more; tensile strength follows at 820 MPa (119 ksi) vs 560 MPa (81.2 ksi). In exchange, 904L Annealed is the more ductile: elongation 45% versus 15% for 904L Cold Rolled Hard, and 904L Cold Rolled Hard is harder (260 HB vs 150 HB). 904L Annealed runs hotter in service (400°C vs 300°C continuous).
904L AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
904L Cold Rolled HardChoose it when strength drives the design.
904L Annealed vs 904L Cold Rolled Hard: 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.
