Stainless Steel S82122 Annealed vs S82122-CD
Stainless Steel · S82122 temper comparison
S82122 Annealed and S82122-CD are two conditions of the same stainless steel grade, S82122: Annealed versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. S82122-CD is the stronger of the two: yield strength 700 MPa (102 ksi) against 520 MPa (75.4 ksi) for S82122 Annealed, about 35% more; tensile strength follows at 860 MPa (125 ksi) vs 720 MPa (104 ksi). In exchange, S82122 Annealed is the more ductile: elongation 30% versus 18% for S82122-CD, and S82122-CD is harder (285 HB vs 240 HB).
S82122 AnnealedChoose it when the part is bent, formed or impact-loaded.
S82122-CDChoose it when strength drives the design.
S82122 Annealed vs S82122-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.
