Steel A182 F11 Cl.1-ANN vs A182 F11 Cl.1 NT-CL2
Steel · A182 F11 Cl.1 temper comparison
A182 F11 Cl.1-ANN and A182 F11 Cl.1 NT-CL2 are two conditions of the same steel grade, A182 F11 Cl.1: ANN (annealed) versus NT-CL2 (class 2). The chemistry is identical, so every difference below comes from the condition. A182 F11 Cl.1 NT-CL2 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 275 MPa (39.9 ksi) for A182 F11 Cl.1-ANN, about 38% more; tensile strength follows at 550 MPa (79.8 ksi) vs 480 MPa (69.6 ksi). In exchange, A182 F11 Cl.1-ANN is the more ductile: elongation 30% versus 25% for A182 F11 Cl.1 NT-CL2, and A182 F11 Cl.1 NT-CL2 is harder (170 HB vs 115 HB).

A182 F11 Cl.1-ANN vs A182 F11 Cl.1 NT-CL2: 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.
