Steel 1015-CD vs 1015 Normalized
Steel · 1015 temper comparison
1015-CD and 1015 Normalized are two conditions of the same steel grade, 1015: CD (cold drawn) versus Normalized. The chemistry is identical, so every difference below comes from the condition. 1015 Normalized is the stronger of the two: tensile strength 424 MPa (61.5 ksi) against 385 MPa (55.8 ksi) for 1015-CD, about 10% more. 1015 Normalized is the more ductile: elongation 37% versus 18% for 1015-CD, and 1015 Normalized is harder (121 HB vs 111 HB).
1015 NormalizedChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1015-CD vs 1015 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.

1015-CD vs 1015 Normalized — frequently asked
Is 1015 Normalized stronger than 1015-CD?
Yes. 1015 Normalized has a typical tensile strength of 424 MPa (61.5 ksi) against 385 MPa (55.8 ksi) for 1015-CD — about 10% more.
Which condition does FabDigit quote by default, CD or Normalized?
HR is the default 1015 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 1015-CD over 1015 Normalized?
Pick 1015 Normalized when strength drives the design, or when the part is bent, formed or impact-loaded.
