Stainless Steel 1.4854-CD vs 1.4854-SA
Stainless Steel · 1.4854 temper comparison
1.4854-CD and 1.4854-SA are two conditions of the same stainless steel grade, 1.4854: CD (cold drawn) versus SA (solution Annealed). The chemistry is identical, so every difference below comes from the condition. 1.4854-CD is the stronger of the two: yield strength 570 MPa (82.7 ksi) against 330 MPa (47.9 ksi) for 1.4854-SA, about 73% more; tensile strength follows at 870 MPa (126 ksi) vs 750 MPa (109 ksi). In exchange, 1.4854-SA is the more ductile: elongation 45% versus 25% for 1.4854-CD, and 1.4854-CD is harder (250 HB vs 190 HB).
1.4854-CDChoose it when strength drives the design.
1.4854-SAChoose it when the part is bent, formed or impact-loaded.
1.4854-CD vs 1.4854-SA: 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.
