Steel 35NiCrMo16 +A vs 35NiCrMo16 +N
Steel · 35NiCrMo16 temper comparison
35NiCrMo16 +A and 35NiCrMo16 +N are two conditions of the same steel grade, 35NiCrMo16: +A (annealed) versus +N (normalized). The chemistry is identical, so every difference below comes from the condition. 35NiCrMo16 +N is the stronger of the two: yield strength 800 MPa (116 ksi) against 620 MPa (89.9 ksi) for 35NiCrMo16 +A, about 29% more; tensile strength follows at 1,150 MPa (167 ksi) vs 900 MPa (131 ksi). In exchange, 35NiCrMo16 +A is the more ductile: elongation 16% versus 13% for 35NiCrMo16 +N, and 35NiCrMo16 +N is harder (340 HB vs 265 HB).

35NiCrMo16 +A vs 35NiCrMo16 +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.

35NiCrMo16 +A vs 35NiCrMo16 +N — frequently asked
Is 35NiCrMo16 +N stronger than 35NiCrMo16 +A?
Yes. 35NiCrMo16 +N has a typical yield strength of 800 MPa (116 ksi) against 620 MPa (89.9 ksi) for 35NiCrMo16 +A — about 29% more. Tensile strength is 1,150 MPa (167 ksi) vs 900 MPa (131 ksi).
Which condition does FabDigit quote by default, +A or +N?
+QT-1250 is the default 35NiCrMo16 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, 35NiCrMo16 +A or 35NiCrMo16 +N?
35NiCrMo16 +A, by a small margin. Both rate fair for machinability — 45/100 against 36/100 for 35NiCrMo16 +N; for welding the order is 35NiCrMo16 +N first (poor, 20/100) then 35NiCrMo16 +A (poor, 15/100).
