Steel 9254-CD vs 9254 Normalized
Steel · 9254 temper comparison
9254-CD and 9254 Normalized are two conditions of the same steel grade, 9254: CD (cold drawn) versus Normalized. The chemistry is identical, so every difference below comes from the condition. 9254-CD is the stronger of the two: yield strength 950 MPa (138 ksi) against 660 MPa (95.7 ksi) for 9254 Normalized, about 44% more; tensile strength follows at 1,150 MPa (167 ksi) vs 1,030 MPa (149 ksi). In exchange, 9254 Normalized is the more ductile: elongation 14% versus 7% for 9254-CD, and 9254-CD is harder (330 HB vs 300 HB). 9254 Normalized runs hotter in service (250°C vs 200°C continuous).
9254-CDChoose it when strength drives the design.
9254 NormalizedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
9254-CD vs 9254 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.

9254-CD vs 9254 Normalized — frequently asked
Is 9254-CD stronger than 9254 Normalized?
Yes. 9254-CD has a typical yield strength of 950 MPa (138 ksi) against 660 MPa (95.7 ksi) for 9254 Normalized — about 44% more. Tensile strength is 1,150 MPa (167 ksi) vs 1,030 MPa (149 ksi).
Which condition does FabDigit quote by default, CD or Normalized?
HR is the default 9254 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.
Which is easier to machine, 9254-CD or 9254 Normalized?
9254-CD, by a small margin. Both rate fair for machinability — 42/100 against 36/100 for 9254 Normalized.
