Steel 4330V-CD vs 4330V Normalized
Steel · 4330V temper comparison
4330V-CD and 4330V Normalized are two conditions of the same steel grade, 4330V: CD (cold drawn) versus Normalized. The chemistry is identical, so every difference below comes from the condition. 4330V Normalized is the stronger of the two: tensile strength 1,035 MPa (150 ksi) against 900 MPa (131 ksi) for 4330V-CD, about 15% more. 4330V Normalized is the more ductile: elongation 16% versus 12% for 4330V-CD, and 4330V Normalized is harder (302 HB vs 269 HB). On the shop floor, 4330V-CD machines more easily (good vs fair).
4330V-CDChoose it when the part is machined in volume.
4330V NormalizedChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
4330V-CD vs 4330V 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.

4330V-CD vs 4330V Normalized — frequently asked
Is 4330V Normalized stronger than 4330V-CD?
Yes. 4330V Normalized has a typical tensile strength of 1,035 MPa (150 ksi) against 900 MPa (131 ksi) for 4330V-CD — about 15% more.
Which condition does FabDigit quote by default, CD or Normalized?
HR is the default 4330V 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, 4330V-CD or 4330V Normalized?
4330V-CD. Its machinability rates good (55/100) against fair (45/100) for 4330V Normalized.
