Steel GX10CrMoV9-1-ANN vs GX10CrMoV9-1 Q+T
Steel · GX10CrMoV9-1 temper comparison
GX10CrMoV9-1-ANN and GX10CrMoV9-1 Q+T are two conditions of the same steel grade, GX10CrMoV9-1: ANN (annealed) 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 360 MPa (52.2 ksi) for GX10CrMoV9-1-ANN, about 44% more; tensile strength follows at 700 MPa (102 ksi) vs 580 MPa (84.1 ksi). In exchange, GX10CrMoV9-1-ANN is the more ductile: elongation 24% versus 20% for GX10CrMoV9-1 Q+T, and GX10CrMoV9-1 Q+T is harder (230 HB vs 180 HB). GX10CrMoV9-1 Q+T runs hotter in service (600°C vs 450°C continuous). On the shop floor, GX10CrMoV9-1-ANN machines more easily (good vs fair).

GX10CrMoV9-1-ANN 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.

GX10CrMoV9-1-ANN vs GX10CrMoV9-1 Q+T — frequently asked
Is GX10CrMoV9-1 Q+T stronger than GX10CrMoV9-1-ANN?
Yes. GX10CrMoV9-1 Q+T has a typical yield strength of 520 MPa (75.4 ksi) against 360 MPa (52.2 ksi) for GX10CrMoV9-1-ANN — about 44% more. Tensile strength is 700 MPa (102 ksi) vs 580 MPa (84.1 ksi).
Which condition does FabDigit quote by default, ANN or Q+T?
N+T is the default GX10CrMoV9-1 condition in the FabDigit quote flow (neither ANN nor Q+T). 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, GX10CrMoV9-1-ANN or GX10CrMoV9-1 Q+T?
GX10CrMoV9-1-ANN. Its machinability rates good (55/100) against fair (42/100) for GX10CrMoV9-1 Q+T; for welding the order is GX10CrMoV9-1-ANN first (fair, 40/100) then GX10CrMoV9-1 Q+T (fair, 35/100).
