Steel A182 F11 Cl.2 N+T vs A182 F11 Cl.2 Q+T
Steel · A182 F11 Cl.2 temper comparison
A182 F11 Cl.2 N+T and A182 F11 Cl.2 Q+T are two conditions of the same steel grade, A182 F11 Cl.2: N+T (normalized and tempered) versus Q+T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. A182 F11 Cl.2 Q+T is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 350 MPa (50.8 ksi) for A182 F11 Cl.2 N+T, about 29% more; tensile strength follows at 610 MPa (88.5 ksi) vs 550 MPa (79.8 ksi). In exchange, A182 F11 Cl.2 N+T is the more ductile: elongation 26% versus 23% for A182 F11 Cl.2 Q+T, and A182 F11 Cl.2 Q+T is harder (187 HB vs 163 HB).
A182 F11 Cl.2 N+TChoose it when the part is bent, formed or impact-loaded.
A182 F11 Cl.2 Q+TChoose it when strength drives the design.
A182 F11 Cl.2 N+T vs A182 F11 Cl.2 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.
