Steel 60CrMnA-A vs 60CrMnA-N
Steel · 60CrMnA temper comparison
60CrMnA-A and 60CrMnA-N are two conditions of the same steel grade, 60CrMnA: A (solution annealed) versus N (normalized). The chemistry is identical, so every difference below comes from the condition. 60CrMnA-N is the stronger of the two: yield strength 630 MPa (91.4 ksi) against 430 MPa (62.4 ksi) for 60CrMnA-A, about 47% more; tensile strength follows at 1,000 MPa (145 ksi) vs 730 MPa (106 ksi). In exchange, 60CrMnA-A is the more ductile: elongation 20% versus 13% for 60CrMnA-N, and 60CrMnA-N is harder (300 HB vs 217 HB). 60CrMnA-N runs hotter in service (400°C vs 250°C continuous) and 60CrMnA-N conducts electricity better (9 % IACS vs 8 % IACS). On the shop floor, 60CrMnA-A machines more easily (50 vs 38 out of 100).
60CrMnA-AChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
60CrMnA-NChoose it when strength drives the design, or when the part sees heat.
60CrMnA-A vs 60CrMnA-N: 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.

60CrMnA-A vs 60CrMnA-N — frequently asked
Is 60CrMnA-N stronger than 60CrMnA-A?
Yes. 60CrMnA-N has a typical yield strength of 630 MPa (91.4 ksi) against 430 MPa (62.4 ksi) for 60CrMnA-A — about 47% more. Tensile strength is 1,000 MPa (145 ksi) vs 730 MPa (106 ksi).
Which condition does FabDigit quote by default, A or N?
QT is the default 60CrMnA 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, 60CrMnA-A or 60CrMnA-N?
60CrMnA-A, by a small margin. Both rate fair for machinability — 50/100 against 38/100 for 60CrMnA-N; for welding the order is 60CrMnA-N first (poor, 22/100) then 60CrMnA-A (poor, 15/100).
