Stainless Steel S44625-ANN vs S44625-CD
Stainless Steel · S44625 temper comparison
S44625-ANN and S44625-CD are two conditions of the same stainless steel grade, S44625: ANN (annealed) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. S44625-CD is the stronger of the two: yield strength 500 MPa (72.5 ksi) against 380 MPa (55.1 ksi) for S44625-ANN, about 32% more; tensile strength follows at 600 MPa (87 ksi) vs 500 MPa (72.5 ksi). In exchange, S44625-ANN is the more ductile: elongation 28% versus 16% for S44625-CD, and S44625-CD is harder (210 HB vs 175 HB).

S44625-ANN vs S44625-CD: 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.
