Steel 17CrNiMo6 Normalized vs 17CrNiMo6 +S
Steel · 17CrNiMo6 temper comparison
17CrNiMo6 Normalized and 17CrNiMo6 +S are two conditions of the same steel grade, 17CrNiMo6: Normalized versus +S (treated for shearability). The chemistry is identical, so every difference below comes from the condition. 17CrNiMo6 Normalized is the stronger of the two: yield strength 560 MPa (81.2 ksi) against 480 MPa (69.6 ksi) for 17CrNiMo6 +S, about 17% more; tensile strength follows at 880 MPa (128 ksi) vs 780 MPa (113 ksi). 17CrNiMo6 Normalized is harder — 260 HB against 225 HB for 17CrNiMo6 +S — which matters for wear surfaces and threads. On the shop floor, 17CrNiMo6 +S forms better (48 vs 35 out of 100).

17CrNiMo6 Normalized vs 17CrNiMo6 +S: 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.

17CrNiMo6 Normalized vs 17CrNiMo6 +S — frequently asked
Is 17CrNiMo6 Normalized stronger than 17CrNiMo6 +S?
Yes. 17CrNiMo6 Normalized has a typical yield strength of 560 MPa (81.2 ksi) against 480 MPa (69.6 ksi) for 17CrNiMo6 +S — about 17% more. Tensile strength is 880 MPa (128 ksi) vs 780 MPa (113 ksi).
Which condition does FabDigit quote by default, Normalized or +S?
Annealed is the default 17CrNiMo6 condition in the FabDigit quote flow (neither Normalized nor +S). 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, 17CrNiMo6 Normalized or 17CrNiMo6 +S?
17CrNiMo6 +S, by a small margin. Both rate fair for machinability — 48/100 against 42/100 for 17CrNiMo6 Normalized.
