Steel 1141-CD vs 1141 Normalized
Steel · 1141 temper comparison
1141-CD and 1141 Normalized are two conditions of the same steel grade, 1141: CD (cold drawn) versus Normalized. The chemistry is identical, so every difference below comes from the condition. 1141-CD is the stronger of the two: yield strength 640 MPa (92.8 ksi) against 405 MPa (58.7 ksi) for 1141 Normalized, about 58% more; tensile strength follows at 765 MPa (111 ksi) vs 706 MPa (102 ksi). In exchange, 1141 Normalized is the more ductile: elongation 22.7% versus 10% for 1141-CD, and 1141-CD is harder (217 HB vs 201 HB).
1141-CDChoose it when strength drives the design.
1141 NormalizedChoose it when the part is bent, formed or impact-loaded.
1141-CD vs 1141 Normalized: 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.

1141-CD vs 1141 Normalized — frequently asked
Is 1141-CD stronger than 1141 Normalized?
Yes. 1141-CD has a typical yield strength of 640 MPa (92.8 ksi) against 405 MPa (58.7 ksi) for 1141 Normalized — about 58% more. Tensile strength is 765 MPa (111 ksi) vs 706 MPa (102 ksi).
Which condition does FabDigit quote by default, CD or Normalized?
HR is the default 1141 condition in the FabDigit quote flow (neither CD nor Normalized). 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 1141-CD over 1141 Normalized?
Pick 1141-CD when strength drives the design. Pick 1141 Normalized when the part is bent, formed or impact-loaded.
