Steel A182 F22V-QT vs A182 F22V QT+SPWHT
Steel · A182 F22V temper comparison
A182 F22V-QT and A182 F22V QT+SPWHT are two conditions of the same steel grade, A182 F22V: QT (quenched and tempered) versus QT+SPWHT (Q&T + simulated post-weld heat treatment). The chemistry is identical, so every difference below comes from the condition. A182 F22V-QT is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 455 MPa (66 ksi) for A182 F22V QT+SPWHT, about 5% more; tensile strength follows at 655 MPa (95 ksi) vs 620 MPa (89.9 ksi).

A182 F22V-QT vs A182 F22V QT+SPWHT: 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.
