Stainless Steel 310Cb Annealed vs 310Cb-CD
Stainless Steel · 310Cb temper comparison
310Cb Annealed and 310Cb-CD are two conditions of the same stainless steel grade, 310Cb: Annealed versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 310Cb-CD is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 310 MPa (45 ksi) for 310Cb Annealed, about 77% more; tensile strength follows at 760 MPa (110 ksi) vs 620 MPa (89.9 ksi). In exchange, 310Cb Annealed is the more ductile: elongation 45% versus 25% for 310Cb-CD, and 310Cb-CD is harder (225 HB vs 160 HB).
310Cb AnnealedChoose it when the part is bent, formed or impact-loaded.
310Cb-CDChoose it when strength drives the design.
310Cb Annealed vs 310Cb-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.
