Stainless Steel 15Cr25Ti Annealed vs 15Cr25Ti-CD
Stainless Steel · 15Cr25Ti temper comparison
15Cr25Ti Annealed and 15Cr25Ti-CD are two conditions of the same stainless steel grade, 15Cr25Ti: Annealed versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 15Cr25Ti-CD is the stronger of the two: yield strength 500 MPa (72.5 ksi) against 300 MPa (43.5 ksi) for 15Cr25Ti Annealed, about 67% more; tensile strength follows at 640 MPa (92.8 ksi) vs 520 MPa (75.4 ksi). In exchange, 15Cr25Ti Annealed is the more ductile: elongation 22% versus 12% for 15Cr25Ti-CD, and 15Cr25Ti-CD is harder (225 HB vs 180 HB).
15Cr25Ti AnnealedChoose it when the part is bent, formed or impact-loaded.
15Cr25Ti-CDChoose it when strength drives the design.
15Cr25Ti Annealed vs 15Cr25Ti-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.
