Stainless Steel 310HCb Annealed vs 310HCb-CD
Stainless Steel · 310HCb temper comparison
310HCb Annealed and 310HCb-CD are two conditions of the same stainless steel grade, 310HCb: Annealed versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 310HCb-CD is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 260 MPa (37.7 ksi) for 310HCb Annealed, about 73% more; tensile strength follows at 690 MPa (100 ksi) vs 590 MPa (85.6 ksi). In exchange, 310HCb Annealed is the more ductile: elongation 45% versus 30% for 310HCb-CD, and 310HCb-CD is harder (210 HB vs 170 HB).

310HCb Annealed vs 310HCb-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.
