Steel A182 F22V-ANN vs A182 F22V QT+SPWHT
Steel · A182 F22V temper comparison
A182 F22V-ANN and A182 F22V QT+SPWHT are two conditions of the same steel grade, A182 F22V: ANN (annealed) 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+SPWHT is the stronger of the two: yield strength 455 MPa (66 ksi) against 330 MPa (47.9 ksi) for A182 F22V-ANN, about 38% more; tensile strength follows at 620 MPa (89.9 ksi) vs 520 MPa (75.4 ksi). In exchange, A182 F22V-ANN is the more ductile: elongation 26% versus 23% for A182 F22V QT+SPWHT, and A182 F22V QT+SPWHT is harder (195 HB vs 160 HB). A182 F22V QT+SPWHT runs hotter in service (482°C vs 425°C continuous).
A182 F22V-ANNChoose it when the part is bent, formed or impact-loaded.
A182 F22V QT+SPWHTChoose it when strength drives the design, or when the part sees heat.
A182 F22V-ANN 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.

A182 F22V-ANN vs A182 F22V QT+SPWHT — frequently asked
Is A182 F22V QT+SPWHT stronger than A182 F22V-ANN?
Yes. A182 F22V QT+SPWHT has a typical yield strength of 455 MPa (66 ksi) against 330 MPa (47.9 ksi) for A182 F22V-ANN — about 38% more. Tensile strength is 620 MPa (89.9 ksi) vs 520 MPa (75.4 ksi).
Which condition does FabDigit quote by default, ANN or QT+SPWHT?
QT is the default A182 F22V condition in the FabDigit quote flow (neither ANN nor QT+SPWHT). 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 F22V-ANN or A182 F22V QT+SPWHT?
A182 F22V-ANN. Its machinability rates good (55/100) against fair (48/100) for A182 F22V QT+SPWHT; for welding the order is A182 F22V-ANN first (good, 55/100) then A182 F22V QT+SPWHT (fair, 50/100).
