Steel 9Mn2V-CD vs 9Mn2V-N

Steel · 9Mn2V temper comparison

9Mn2V-CD and 9Mn2V-N are two conditions of the same steel grade, 9Mn2V: CD (cold drawn) versus N (normalized). The chemistry is identical, so every difference below comes from the condition. 9Mn2V-N is the stronger of the two: yield strength 650 MPa (94.3 ksi) against 600 MPa (87 ksi) for 9Mn2V-CD, about 8% more; tensile strength follows at 1,000 MPa (145 ksi) vs 800 MPa (116 ksi). In exchange, 9Mn2V-CD is the more ductile: elongation 10% versus 8% for 9Mn2V-N, and 9Mn2V-N is harder (300 HB vs 235 HB). On the shop floor, 9Mn2V-CD machines more easily (good vs poor).

9Mn2V-CDChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

9Mn2V-NChoose it when strength drives the design.

9Mn2V-CD vs 9Mn2V-N — frequently asked

Is 9Mn2V-N stronger than 9Mn2V-CD?

Yes. 9Mn2V-N has a typical yield strength of 650 MPa (94.3 ksi) against 600 MPa (87 ksi) for 9Mn2V-CD — about 8% more. Tensile strength is 1,000 MPa (145 ksi) vs 800 MPa (116 ksi).

Which condition does FabDigit quote by default, CD or N?

A is the default 9Mn2V condition in the FabDigit quote flow (neither CD nor N). 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, 9Mn2V-CD or 9Mn2V-N?

9Mn2V-CD. Its machinability rates good (58/100) against poor (30/100) for 9Mn2V-N; for welding the order is 9Mn2V-CD first (poor, 18/100) then 9Mn2V-N (not recommended, 12/100).
