Steel 1117 Annealed vs 1117-CD
Steel · 1117 temper comparison
1117 Annealed and 1117-CD are two conditions of the same steel grade, 1117: Annealed versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 1117-CD is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 220 MPa (31.9 ksi) for 1117 Annealed, about 89% more; tensile strength follows at 485 MPa (70.3 ksi) vs 405 MPa (58.7 ksi). In exchange, 1117 Annealed is the more ductile: elongation 35% versus 15% for 1117-CD, and 1117-CD is harder (143 HB vs 116 HB).

1117-CDChoose it when strength drives the design.
1117 Annealed vs 1117-CD: 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.

1117 Annealed vs 1117-CD — frequently asked
Is 1117-CD stronger than 1117 Annealed?
Yes. 1117-CD has a typical yield strength of 415 MPa (60.2 ksi) against 220 MPa (31.9 ksi) for 1117 Annealed — about 89% more. Tensile strength is 485 MPa (70.3 ksi) vs 405 MPa (58.7 ksi).
Which condition does FabDigit quote by default, Annealed or CD?
HR is the default 1117 condition in the FabDigit quote flow (neither Annealed nor CD). 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, 1117 Annealed or 1117-CD?
1117-CD. Its machinability rates very good (75/100) against good (66/100) for 1117 Annealed; for welding the order is 1117 Annealed first (fair, 52/100) then 1117-CD (fair, 45/100).
