Steel G35CrNiMo6-6 +N vs G35CrNiMo6-6 +QT2
Steel · G35CrNiMo6-6 temper comparison
G35CrNiMo6-6 +N and G35CrNiMo6-6 +QT2 are two conditions of the same steel grade, G35CrNiMo6-6: +N (normalized) versus +QT2 (quenched and tempered, tough condition). The chemistry is identical, so every difference below comes from the condition. G35CrNiMo6-6 +QT2 is the stronger of the two: yield strength 600 MPa (87 ksi) against 500 MPa (72.5 ksi) for G35CrNiMo6-6 +N, about 20% more. G35CrNiMo6-6 +QT2 is harder — 245 HB against 225 HB for G35CrNiMo6-6 +N — which matters for wear surfaces and threads.
G35CrNiMo6-6 +QT2Choose it when strength drives the design, or when surface hardness matters.
G35CrNiMo6-6 +N vs G35CrNiMo6-6 +QT2: 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.

G35CrNiMo6-6 +N vs G35CrNiMo6-6 +QT2 — frequently asked
Is G35CrNiMo6-6 +QT2 stronger than G35CrNiMo6-6 +N?
Yes. G35CrNiMo6-6 +QT2 has a typical yield strength of 600 MPa (87 ksi) against 500 MPa (72.5 ksi) for G35CrNiMo6-6 +N — about 20% more. Tensile strength is 820 MPa (119 ksi) vs 780 MPa (113 ksi).
Which condition does FabDigit quote by default, +N or +QT2?
+QT1 is the default G35CrNiMo6-6 condition in the FabDigit quote flow (neither +N nor +QT2). 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, G35CrNiMo6-6 +N or G35CrNiMo6-6 +QT2?
G35CrNiMo6-6 +N, by a small margin. Both rate fair for machinability — 48/100 against 42/100 for G35CrNiMo6-6 +QT2.
