Steel GX10CrMoV9-1 N+T vs GX10CrMoV9-1 Q+T
Steel · GX10CrMoV9-1 temper comparison
GX10CrMoV9-1 N+T and GX10CrMoV9-1 Q+T are two conditions of the same steel grade, GX10CrMoV9-1: N+T (normalized and tempered) versus Q+T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. GX10CrMoV9-1 Q+T is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 490 MPa (71.1 ksi) for GX10CrMoV9-1 N+T, about 6% more; tensile strength follows at 700 MPa (102 ksi) vs 660 MPa (95.7 ksi). GX10CrMoV9-1 Q+T is harder — 230 HB against 215 HB for GX10CrMoV9-1 N+T — which matters for wear surfaces and threads.
GX10CrMoV9-1 Q+TChoose it when strength drives the design, or when surface hardness matters.
GX10CrMoV9-1 N+T vs GX10CrMoV9-1 Q+T: 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.
