Steel 1050 Annealed vs 1050-CD
Steel · 1050 temper comparison
1050 Annealed and 1050-CD are two conditions of the same steel grade, 1050: Annealed versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 1050-CD is the stronger of the two: yield strength 580 MPa (84.1 ksi) against 365 MPa (52.9 ksi) for 1050 Annealed, about 59% more; tensile strength follows at 690 MPa (100 ksi) vs 636 MPa (92.2 ksi). In exchange, 1050 Annealed is the more ductile: elongation 24% versus 10% for 1050-CD, and 1050-CD is harder (197 HB vs 187 HB).
1050 AnnealedChoose it when the part is bent, formed or impact-loaded.
1050-CDChoose it when strength drives the design.
1050 Annealed vs 1050-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.

1050 Annealed vs 1050-CD — frequently asked
Is 1050-CD stronger than 1050 Annealed?
Yes. 1050-CD has a typical yield strength of 580 MPa (84.1 ksi) against 365 MPa (52.9 ksi) for 1050 Annealed — about 59% more. Tensile strength is 690 MPa (100 ksi) vs 636 MPa (92.2 ksi).
Which condition does FabDigit quote by default, Annealed or CD?
HR is the default 1050 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.
When should I choose 1050 Annealed over 1050-CD?
Pick 1050 Annealed when the part is bent, formed or impact-loaded. Pick 1050-CD when strength drives the design.
