Steel 16MnCr5-CD vs 16MnCr5-CR
Steel · 16MnCr5 temper comparison
16MnCr5-CD and 16MnCr5-CR are two conditions of the same steel grade, 16MnCr5: CD (cold drawn) versus CR (cold rolled). The chemistry is identical, so every difference below comes from the condition. 16MnCr5-CD is the stronger of the two: yield strength 560 MPa (81.2 ksi) against 380 MPa (55.1 ksi) for 16MnCr5-CR, about 47% more; tensile strength follows at 700 MPa (102 ksi) vs 560 MPa (81.2 ksi). In exchange, 16MnCr5-CR is the more ductile: elongation 18% versus 10% for 16MnCr5-CD, and 16MnCr5-CD is harder (215 HB vs 175 HB). On the shop floor, 16MnCr5-CD machines more easily (good vs fair) and 16MnCr5-CR welds better (good vs fair).
16MnCr5-CDChoose it when strength drives the design, or when the part is machined in volume.
16MnCr5-CRChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
16MnCr5-CD vs 16MnCr5-CR: 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.

16MnCr5-CD vs 16MnCr5-CR — frequently asked
Is 16MnCr5-CD stronger than 16MnCr5-CR?
Yes. 16MnCr5-CD has a typical yield strength of 560 MPa (81.2 ksi) against 380 MPa (55.1 ksi) for 16MnCr5-CR — about 47% more. Tensile strength is 700 MPa (102 ksi) vs 560 MPa (81.2 ksi).
Which condition does FabDigit quote by default, CD or CR?
HR is the default 16MnCr5 condition in the FabDigit quote flow (neither CD nor CR). 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, 16MnCr5-CD or 16MnCr5-CR?
16MnCr5-CD. Its machinability rates good (62/100) against fair (52/100) for 16MnCr5-CR; for welding the order is 16MnCr5-CR first (good, 55/100) then 16MnCr5-CD (fair, 40/100).
