Steel 12Cr1MoV-A vs 12Cr1MoV-N

Steel · 12Cr1MoV temper comparison

12Cr1MoV-A and 12Cr1MoV-N are two conditions of the same steel grade, 12Cr1MoV: A (solution annealed) versus N (normalized). The chemistry is identical, so every difference below comes from the condition. 12Cr1MoV-N is the stronger of the two: yield strength 410 MPa (59.5 ksi) against 245 MPa (35.5 ksi) for 12Cr1MoV-A, about 67% more; tensile strength follows at 620 MPa (89.9 ksi) vs 470 MPa (68.2 ksi). In exchange, 12Cr1MoV-A is the more ductile: elongation 27% versus 20% for 12Cr1MoV-N, and 12Cr1MoV-N is harder (190 HB vs 145 HB). On the shop floor, 12Cr1MoV-A machines more easily (good vs fair).

12Cr1MoV-AChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

12Cr1MoV-NChoose it when strength drives the design.

12Cr1MoV-A vs 12Cr1MoV-N — frequently asked

Is 12Cr1MoV-N stronger than 12Cr1MoV-A?

Yes. 12Cr1MoV-N has a typical yield strength of 410 MPa (59.5 ksi) against 245 MPa (35.5 ksi) for 12Cr1MoV-A — about 67% more. Tensile strength is 620 MPa (89.9 ksi) vs 470 MPa (68.2 ksi).

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

N&T is the default 12Cr1MoV condition in the FabDigit quote flow (neither A 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, 12Cr1MoV-A or 12Cr1MoV-N?

12Cr1MoV-A. Its machinability rates good (62/100) against fair (48/100) for 12Cr1MoV-N; for welding the order is 12Cr1MoV-A first (good, 60/100) then 12Cr1MoV-N (fair, 52/100).
