Steel A182 F92 N+T vs A182 F92 Q+T
Steel · A182 F92 temper comparison
A182 F92 N+T and A182 F92 Q+T are two conditions of the same steel grade, A182 F92: N+T (normalized and tempered) versus Q+T (quenched and tempered). 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 520 MPa (75.4 ksi) for A182 F92 N+T, about 8% more. A182 F92 Q+T is harder — 235 HB against 220 HB for A182 F92 N+T — which matters for wear surfaces and threads.
A182 F92 Q+TChoose it when strength drives the design, or when surface hardness matters.
A182 F92 N+T vs A182 F92 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.
