Steel A182 F2 N+T vs A182 F2 Q&T
Steel · A182 F2 temper comparison
A182 F2 N+T and A182 F2 Q&T are two conditions of the same steel grade, A182 F2: N+T (normalized and tempered) versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. A182 F2 Q&T is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 330 MPa (47.9 ksi) for A182 F2 N+T, about 27% more; tensile strength follows at 585 MPa (84.8 ksi) vs 520 MPa (75.4 ksi). In exchange, A182 F2 N+T is the more ductile: elongation 27% versus 23% for A182 F2 Q&T, and A182 F2 Q&T is harder (185 HB vs 160 HB).
A182 F2 N+TChoose it when the part is bent, formed or impact-loaded.
A182 F2 Q&TChoose it when strength drives the design.
A182 F2 N+T vs A182 F2 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.

A182 F2 N+T vs A182 F2 Q&T — frequently asked
Is A182 F2 Q&T stronger than A182 F2 N+T?
Yes. A182 F2 Q&T has a typical yield strength of 420 MPa (60.9 ksi) against 330 MPa (47.9 ksi) for A182 F2 N+T — about 27% more. Tensile strength is 585 MPa (84.8 ksi) vs 520 MPa (75.4 ksi).
Which condition does FabDigit quote by default, N+T or Q&T?
N+T is the default A182 F2 condition in the FabDigit quote flow. 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 F2 N+T or A182 F2 Q&T?
A182 F2 N+T. Its machinability rates good (58/100) against fair (53/100) for A182 F2 Q&T; for welding the order is A182 F2 N+T first (good, 65/100) then A182 F2 Q&T (good, 60/100).
