Steel 25Cr2MoVA-CD vs 25Cr2MoVA Q&T
Steel · 25Cr2MoVA temper comparison
25Cr2MoVA-CD and 25Cr2MoVA Q&T are two conditions of the same steel grade, 25Cr2MoVA: CD (cold drawn) versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. 25Cr2MoVA Q&T is the stronger of the two: yield strength 850 MPa (123 ksi) against 700 MPa (102 ksi) for 25Cr2MoVA-CD, about 21% more; tensile strength follows at 1,000 MPa (145 ksi) vs 850 MPa (123 ksi). 25Cr2MoVA Q&T is the more ductile: elongation 16% versus 12% for 25Cr2MoVA-CD, and 25Cr2MoVA Q&T is harder (300 HB vs 260 HB). 25Cr2MoVA Q&T runs hotter in service (520°C vs 350°C continuous). On the shop floor, 25Cr2MoVA-CD machines more easily (52 vs 42 out of 100).

25Cr2MoVA-CD vs 25Cr2MoVA Q&T: 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.

25Cr2MoVA-CD vs 25Cr2MoVA Q&T — frequently asked
Is 25Cr2MoVA Q&T stronger than 25Cr2MoVA-CD?
Yes. 25Cr2MoVA Q&T has a typical yield strength of 850 MPa (123 ksi) against 700 MPa (102 ksi) for 25Cr2MoVA-CD — about 21% more. Tensile strength is 1,000 MPa (145 ksi) vs 850 MPa (123 ksi).
Which condition does FabDigit quote by default, CD or Q&T?
Q&T is the default 25Cr2MoVA condition in the FabDigit quote flow. 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, 25Cr2MoVA-CD or 25Cr2MoVA Q&T?
25Cr2MoVA-CD, by a small margin. Both rate fair for machinability — 52/100 against 42/100 for 25Cr2MoVA Q&T.
