Steel En16-CD vs En16-V
Steel · En16 temper comparison
En16-CD and En16-V are two conditions of the same steel grade, En16: CD (cold drawn) versus V (hardened and tempered, 1000–1150 MPa). The chemistry is identical, so every difference below comes from the condition. En16-V is the stronger of the two: yield strength 880 MPa (128 ksi) against 620 MPa (89.9 ksi) for En16-CD, about 42% more; tensile strength follows at 1,075 MPa (156 ksi) vs 800 MPa (116 ksi). En16-V is the more ductile: elongation 14% versus 12% for En16-CD, and En16-V is harder (320 HB vs 240 HB). En16-V runs hotter in service (400°C vs 300°C continuous). On the shop floor, En16-CD machines more easily (good vs fair).
En16-CDChoose it when the part is machined in volume.
En16-VChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
En16-CD vs En16-V: 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.

En16-CD vs En16-V — frequently asked
Is En16-V stronger than En16-CD?
Yes. En16-V has a typical yield strength of 880 MPa (128 ksi) against 620 MPa (89.9 ksi) for En16-CD — about 42% more. Tensile strength is 1,075 MPa (156 ksi) vs 800 MPa (116 ksi).
Which condition does FabDigit quote by default, CD or V?
T is the default En16 condition in the FabDigit quote flow (neither CD nor V). 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, En16-CD or En16-V?
En16-CD. Its machinability rates good (58/100) against fair (40/100) for En16-V.
