Steel 36NiCrMo16 +A vs 36NiCrMo16 +N
Steel · 36NiCrMo16 temper comparison
36NiCrMo16 +A and 36NiCrMo16 +N are two conditions of the same steel grade, 36NiCrMo16: +A (annealed) versus +N (normalized). The chemistry is identical, so every difference below comes from the condition. 36NiCrMo16 +N is the stronger of the two: yield strength 1,050 MPa (152 ksi) against 520 MPa (75.4 ksi) for 36NiCrMo16 +A, about 102% more; tensile strength follows at 1,450 MPa (210 ksi) vs 800 MPa (116 ksi). In exchange, 36NiCrMo16 +A is the more ductile: elongation 16% versus 9% for 36NiCrMo16 +N, and 36NiCrMo16 +N is harder (440 HB vs 235 HB). 36NiCrMo16 +A runs hotter in service (350°C vs 250°C continuous). On the shop floor, 36NiCrMo16 +A machines more easily (fair vs poor) and 36NiCrMo16 +A welds better (poor vs not recommended).

36NiCrMo16 +A vs 36NiCrMo16 +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.

36NiCrMo16 +A vs 36NiCrMo16 +N — frequently asked
Is 36NiCrMo16 +N stronger than 36NiCrMo16 +A?
Yes. 36NiCrMo16 +N has a typical yield strength of 1,050 MPa (152 ksi) against 520 MPa (75.4 ksi) for 36NiCrMo16 +A — about 102% more. Tensile strength is 1,450 MPa (210 ksi) vs 800 MPa (116 ksi).
Which condition does FabDigit quote by default, +A or +N?
+QT-40 is the default 36NiCrMo16 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, 36NiCrMo16 +A or 36NiCrMo16 +N?
36NiCrMo16 +A. Its machinability rates fair (48/100) against poor (22/100) for 36NiCrMo16 +N; for welding the order is 36NiCrMo16 +A first (poor, 25/100) then 36NiCrMo16 +N (not recommended, 12/100).
