Steel 13MnNi6-3-A vs 13MnNi6-3 FORGED-N
Steel · 13MnNi6-3 temper comparison
13MnNi6-3-A and 13MnNi6-3 FORGED-N are two conditions of the same steel grade, 13MnNi6-3: A (solution annealed) versus FORGED-N (forging, normalized). The chemistry is identical, so every difference below comes from the condition. 13MnNi6-3 FORGED-N is the stronger of the two: yield strength 375 MPa (54.4 ksi) against 310 MPa (45 ksi) for 13MnNi6-3-A, about 21% more; tensile strength follows at 540 MPa (78.3 ksi) vs 480 MPa (69.6 ksi). In exchange, 13MnNi6-3-A is the more ductile: elongation 30% versus 24% for 13MnNi6-3 FORGED-N, and 13MnNi6-3 FORGED-N is harder (158 HB vs 140 HB).

13MnNi6-3-A vs 13MnNi6-3 FORGED-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.

13MnNi6-3-A vs 13MnNi6-3 FORGED-N — frequently asked
Is 13MnNi6-3 FORGED-N stronger than 13MnNi6-3-A?
Yes. 13MnNi6-3 FORGED-N has a typical yield strength of 375 MPa (54.4 ksi) against 310 MPa (45 ksi) for 13MnNi6-3-A — about 21% more. Tensile strength is 540 MPa (78.3 ksi) vs 480 MPa (69.6 ksi).
Which condition does FabDigit quote by default, A or FORGED-N?
N is the default 13MnNi6-3 condition in the FabDigit quote flow (neither A nor FORGED-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, 13MnNi6-3-A or 13MnNi6-3 FORGED-N?
13MnNi6-3-A, by a small margin. Both rate good for machinability — 64/100 against 58/100 for 13MnNi6-3 FORGED-N.
