Steel 1022 Annealed vs 1022-CR
Steel · 1022 temper comparison
1022 Annealed and 1022-CR are two conditions of the same steel grade, 1022: Annealed versus CR (cold rolled). The chemistry is identical, so every difference below comes from the condition. 1022-CR is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 275 MPa (39.9 ksi) for 1022 Annealed, about 38% more; tensile strength follows at 460 MPa (66.7 ksi) vs 415 MPa (60.2 ksi). In exchange, 1022 Annealed is the more ductile: elongation 30% versus 14% for 1022-CR, and 1022-CR is harder (135 HB vs 111 HB). 1022 Annealed runs hotter in service (400°C vs 350°C continuous). On the shop floor, 1022-CR machines more easily (65 vs 55 out of 100).
1022 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1022-CRChoose it when strength drives the design, or when the part is machined in volume.
1022 Annealed vs 1022-CR: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all 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.

1022 Annealed vs 1022-CR — frequently asked
Is 1022-CR stronger than 1022 Annealed?
Yes. 1022-CR has a typical yield strength of 380 MPa (55.1 ksi) against 275 MPa (39.9 ksi) for 1022 Annealed — about 38% more. Tensile strength is 460 MPa (66.7 ksi) vs 415 MPa (60.2 ksi).
Which condition does FabDigit quote by default, Annealed or CR?
HR is the default 1022 condition in the FabDigit quote flow (neither Annealed nor CR). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, 1022 Annealed or 1022-CR?
1022-CR, by a small margin. Both rate good for machinability — 65/100 against 55/100 for 1022 Annealed.
