Steel 13CrMoV9-10 +A vs 13CrMoV9-10 +N

Steel · 13CrMoV9-10 temper comparison

13CrMoV9-10 +A and 13CrMoV9-10 +N are two conditions of the same steel grade, 13CrMoV9-10: +A (annealed) versus +N (normalized). The chemistry is identical, so every difference below comes from the condition. 13CrMoV9-10 +N is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 330 MPa (47.9 ksi) for 13CrMoV9-10 +A, about 58% more; tensile strength follows at 750 MPa (109 ksi) vs 560 MPa (81.2 ksi). In exchange, 13CrMoV9-10 +A is the more ductile: elongation 24% versus 16% for 13CrMoV9-10 +N, and 13CrMoV9-10 +N is harder (240 HB vs 170 HB). On the shop floor, 13CrMoV9-10 +A machines more easily (good vs fair).

13CrMoV9-10 +AChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

13CrMoV9-10 +A vs 13CrMoV9-10 +N — frequently asked

Is 13CrMoV9-10 +N stronger than 13CrMoV9-10 +A?

Yes. 13CrMoV9-10 +N has a typical yield strength of 520 MPa (75.4 ksi) against 330 MPa (47.9 ksi) for 13CrMoV9-10 +A — about 58% more. Tensile strength is 750 MPa (109 ksi) vs 560 MPa (81.2 ksi).

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

+QT is the default 13CrMoV9-10 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, 13CrMoV9-10 +A or 13CrMoV9-10 +N?

13CrMoV9-10 +A. Its machinability rates good (55/100) against fair (38/100) for 13CrMoV9-10 +N; for welding the order is 13CrMoV9-10 +A first (fair, 50/100) then 13CrMoV9-10 +N (fair, 42/100).
