Steel A182 F92 Q+T vs A182 F92 SUBANN
Steel · A182 F92 temper comparison
A182 F92 Q+T and A182 F92 SUBANN are two conditions of the same steel grade, A182 F92: Q+T (quenched and tempered) versus SUBANN (sub-critical annealed). The chemistry is identical, so every difference below comes from the condition. A182 F92 Q+T is the stronger of the two: yield strength 560 MPa (81.2 ksi) against 400 MPa (58 ksi) for A182 F92 SUBANN, about 40% more; tensile strength follows at 745 MPa (108 ksi) vs 630 MPa (91.4 ksi). In exchange, A182 F92 SUBANN is the more ductile: elongation 26% versus 21% for A182 F92 Q+T, and A182 F92 Q+T is harder (235 HB vs 185 HB). A182 F92 Q+T runs hotter in service (620°C vs 500°C continuous). On the shop floor, A182 F92 SUBANN machines more easily (50 vs 35 out of 100).
A182 F92 Q+TChoose it when strength drives the design, or when the part sees heat.
A182 F92 SUBANNChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
A182 F92 Q+T vs A182 F92 SUBANN: 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.

A182 F92 Q+T vs A182 F92 SUBANN — frequently asked
Is A182 F92 Q+T stronger than A182 F92 SUBANN?
Yes. A182 F92 Q+T has a typical yield strength of 560 MPa (81.2 ksi) against 400 MPa (58 ksi) for A182 F92 SUBANN — about 40% more. Tensile strength is 745 MPa (108 ksi) vs 630 MPa (91.4 ksi).
Which condition does FabDigit quote by default, Q+T or SUBANN?
N+T is the default A182 F92 condition in the FabDigit quote flow (neither Q+T nor SUBANN). 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, A182 F92 Q+T or A182 F92 SUBANN?
A182 F92 SUBANN, by a small margin. Both rate fair for machinability — 50/100 against 35/100 for A182 F92 Q+T; for welding the order is A182 F92 SUBANN first (fair, 45/100) then A182 F92 Q+T (fair, 40/100).
